1947749 - Update KASM Version - Firefox "paste" button overlay (not happening on other browsers)

Status: UNCONFIRMED

(Web Compatibility :: Site Reports, defect, P3)

Description

[amar4665]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/133.0.0.0 Safari/537.36

Steps to reproduce:

Open KASM (v1.14.0.32d10f) on Firefox
Open any workspace browser (firefox / chrome / brave / Ubuntu OS desktop)
Left Click on the address bar (on browsers) or any areas within the workspace for desktops (e.g. Ubuntu desktop)

Actual results:

When I use KASM (v1.14.0.32d10f) on Firefox and open any Workspace (firefox / chrome / brave / Ubuntu OS desktop), when I left click onto the workspace (whether it's a browser or an OS GUI), an overlay of "paste" button appears. This happens even though there is nothing on the Clipboard. See screenshots.

This bug appears when I first click into the workspace, after using the workspace, it will stop appearing (for a while), but sometimes it will show up intermittently which is VERY ANNOYING.

Expected results:

The overlay "paste" button will appear

There is no screenshot.

Does it work if you start Firefox in Troubleshoot mode?

The link doesn't work, I'm guessing it's private from the URL…

Please attach the image to the bug (there's an "Attach New File" above the first comment).

Moving to Web Compatibility for now.

Note: the question about troubleshoot mode is still not answered.

After Testing in Troubleshoot mode the Problem still remains.
The Troubleshoot mode shouldn't make any difference because its a function that shouldnt be triggered even without the troubleshoot mode.

To clarify:

Expected results
The overlay "paste" button doesn't appear

This Paste overlay is deliberate so that sites can't read the user's clipboard without the user knowing. This happens if they call the async clipboard API. We should try to talk to them.
