Example: https://runner.telerik.io/fullscreen/yypoqSea

This example is based on the example from the docs with `navigatable: true` and enough data that the user needs to scroll in order to see the bottom row.

On Chrome on macOS, the filter menu cannot be used when `navigatable: true` and "Tap to click" is enabled in the macOS Trackpad settings. When clicking on the filter icon, the menu disappears very quickly (see screen recording). As a workaround, setting `navigatable` to false seems to resolve the problem. The same issue does not seem to occur on Safari, however, there is still odd behavior with the scrolling.

For some reason, screen size, resolution, and window settings impact the ability to reproduce the issue. The most reliable way for me to reproduce the issue was with Chrome in full screen on a 16-inch MacBook (13-inch works too) with the bookmarks bar showing and no external displays connected. Hiding the bookmarks bar or not using full screen seems to make it more difficult to reproduce.

The documentation of the Kendo-UI Diagram widget specifies the following signature of the zoom method (as do the corresponding TS typings):

zoom(zoom: number, point: kendo.dataviz.diagram.Point): void;

However, the JS implementation looks like this:

zoom: function(zoom, options)

where options is an object that may contain a field called "point" of type kendo.dataviz.diagram.Point.

When using zoom as documented, it ignores the specified point. This DOJO demonstrates the behavior.

The issue is a regression starting with 2024.4.1112

Environment

• Kendo UI version: 2024.4.1112
• Browser: [all]

Steps to reproduce the problem:

Have a grid with:

• specified width (e.g: 1000)
• column virtualization
• multiple columns with a width of 100, but most of them hidden in initial state (e.g.: 50 total, but only 8 shown)
• columnMenu true
• resizable true
  

When running the code that create the grid, the initial state looks like this:

Current behavior:

The header columns are filling the width of the grid (each bigger than the specified 100), but the rows columns cells have the specified width of 100, causing a misalignment.

However, changing the width of a column with the resize handle fixes all the widths (header + rows). 
Same thing for adding/removing a column from the menu.

See the attached video for an example.

If in the initial state there are more shown columns so they can fill the grid width (and have the horizontal scrollbar), the issue is not present.

Expected behavior:

Rows columns should always match the width of the header.

Dojo example:

Here's an example, based on the one from https://demos.telerik.com/kendo-ui/grid/column-virtualization 

https://dojo.telerik.com/@pgarand/UfEkIGiD
