Code Editor File Dropdown Bug
Description
Graphical bug when hovering over the File dropdown in the Code Editor. The red highlighted box below indicates the area for which the dropdown is unresponsive.

- Browser/Platforms - Chrome, Firefox (Windows 11)
Steps to Reproduce
- Visit any valid Code Editor https://playcanvas.com/editor/code/{any_id}
- Hover over the
Filedropdown option - The button is only clickable and the hover effect only shows in the lower and right portion of the option
Looks like it's the drag handle for the PCUI tree view:
If you try to drag a tree view item, the 'invisible' drag handle disappears from the top left corner.
I'm wondering if this should be created hidden: https://github.com/playcanvas/pcui/blob/main/src/components/TreeView/index.ts#L196
Yes since the drag handle item will be hidden once the drag action has been completed already restoring the File dropdown to perform as intended.
This was fixed here: https://github.com/playcanvas/pcui/pull/364
Should be fixed once we've bumped the Editor to the latest version of PCUI.
