Current behavior

A js exception is thrown:
kendo.all.js:78925 Uncaught DOMException: Failed to execute 'setStart' on 'Range': There is no child at offset 3.

Expected/desired behavior

No exceptions.

Environment

• Kendo UI version: 2020.2.617
• jQuery version: x.y
• Browser: [ Chrome XX ]

Bug report

The last row of a table in the Editor cannot be resized.

Reproduction of the problem

1. Open this demo - https://demos.telerik.com/kendo-ui/editor/table-editing.
2. Try resizing the last row.

Current behavior

The upper row will be resized instead.

Expected/desired behavior

The last row should be resized.

Environment

• Kendo UI version: 2020.2.617
• Browser: [all]

Description of the occurring behavior

the styling of links is handled inconsistently:

• When you set the cursor inside a link and then change the text-color the color is changed.
• When you select a block of text containing a link and style the entire block of text (e.g. change the color) and then you try to change the color of the link this has no effect.

The issue seems to be that in the first case a span is inserted inside the a-tag, while in the second case a span is created around the a-tag and the styling for the a-tag is then used.

Reproduction of the problem

This can be reproduced in the All Tools demo as shown in the following video.

NOTE: if only the link is selected, or the selection starts or ends with the link, then the link color is changed. The issue is reproducible only when there is selected text before and after the link.

Expected/desired behavior

The color should be applied to the link text too.

Environment

• Kendo UI version: 2025.1.227
• Browser: [All]

Bug report

Using Edge/Chrome, upon pasting underline text in the Kendo UI Editor, the content is rendered underline, but the UI doesn't highlight the button. In turn, if the user toggles the underline style for parts of the text, it doesn't work. At this point, the button is now highlighted for the part, but switching back to no underline style doesn't have any effect regarding the rendering. Removing the style for the whole line does work as expected.

Reproduction of the problem

1. Open Editor demo and enter some text, containing an underline.

2. Copy the entered text and reload page
3. Paste content at the start of the document. The text is not recognized as underline text

4. Select part of the text and toggle underline. Part of the text is recognized as underlined text now.

Expected/desired behavior

The underlined text decoration should be recognized by the UI and display.

Additional Notes

As a comparison, here is the content after paste:

Edge/Chrome

<p><span style="text-decoration-line:underline;">some text with underline</span></p>

FireFox - which is working

<p><span style="text-decoration:underline;">some text with underline</span></p>

Environment

• Kendo UI version: 2023.1.314
• jQuery version: All supported versions

1. use safari browser

2. Go to https://demos.telerik.com/kendo-ui/editor/index

3.  copy a long text over 25 characters

Bug report

The ColorPickers in the Editor allow the user to change the text color or the background color of a selection in the component. When the Editor is working in Inline mode, if you select a text and manually enter a value in the HEX input of a ColorPicker, the pre-selected text is no longer selected. No text is colored inside the Editor.

Reproduction of the problem

1. Open this Dojo and run it
2. Select a text in the inline Editor
3. Open one of the ColorPickers and enter a value in the HEX input
4. Apply the HEX value

Current behavior

The ColorPicker closes. The selected text in the Editor before opening the ColorPicker is no longer selected. No text in the Editor is in the color entered in the HEX editor.

Expected/desired behavior

Clicking on the Apply button of the ColorPicker, after a HEX value is entered, should close the ColorPicker and color the pre-selected text. This correct behavior can be observed in the second Editor in the linked above Dojo example.
