Inconsistent behavior between Firefox and Chrome (other browser not tested) when cutting and pasting content within the editor.
We have more advanced cases but I tried to simplify the case here as much as I could.
This has been tested on you demo page at https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
I have tested using Firefox 88 and Chrome 90, both on Widows 10.
Reproduce:
Paste the following content in html-mode:
<p>Lorem ipsum dolor sit amet.</p>
<p>Ut enim ad minim veniam.</p>
<figure>
<img src="../../images/attractions_LosGigantes.png" alt="Test">
<figcaption>Image text</figcaption>
</figure>
<p>Excepteur sint occaecat cupidatat non proident.</p>
Switch to designmode.
Mark text, including the dot after veniam until before the first character in Excepteur
Cut
(First difference noted here)
Goto after Lorum Ipsum
Paste
(Second difference here)
First difference:
In Chrome you get:
<p>Lorem ipsum dolor sit amet.</p>
<p>Ut enim ad minim veniamExcepteur sint occaecat cupidatat non proident.</p>
In Firefox you get:
<p>Lorem ipsum dolor sit amet.</p>
<p>Ut enim ad minim veniam</p>
<p>Excepteur sint occaecat cupidatat non proident.</p>
Second difference:
Chrome:
<p>Lorem ipsum</p>
<p>.</p>
<p><figure><img src="https://demos.telerik.com/aspnet-ajax/editor/images/attractions_LosGigantes.png" alt="Test" /><figcaption>Image text</figcaption>
<div> </div>
</figure> dolor sit amet.</p>
<p>Ut enim ad minim veniamExcepteur sint occaecat cupidatat non proident.</p>
Firefox:
<p>Lorem ipsum.
<figure>
<img src="https://demos.telerik.com/aspnet-ajax/editor/images/attractions_LosGigantes.png" alt="Test" />
<figcaption>Image text</figcaption>
</figure>
dolor sit amet.</p>
<p>Ut enim ad minim veniam</p>
<p>Excepteur sint occaecat cupidatat non proident.</p>
