What happened?

When using the browser's Glance feature, if a webpage is opened in another workspace at the same time, the browser becomes unresponsive — you can't click on anything or scroll the page.

Steps to Reproduce

1. Press Ctrl + T to open a new tab and navigate to any website.
2. Alt + Click on a hyperlink to open it in the Glance view.
3. Switch to another workspace and open a new tab.
4. Return to the original workspace and try to interact with the page.
5. Observe that the page becomes frozen — clicks and scrolling don’t work.

Wierd. I was able to reproduce this only at first try and no more afterwards. Probably there are other conditions needed to be met.

If someone has any more info on how to reproduce, please let me know!

I found that if you wait for the webpage in the other workspace to fully load, and then return to the original workspace where Glance is active, the browser will freeze.
Alternatively, you can also try opening multiple webpages consecutively in another workspace, and then switching back to the Glance page — this can also reliably reproduce the bug.

Oh, yes, this has a higher sucesseful rate of reproducing.

One thing I found is that when you do the step4: Return to the original workspace and try to interact with the page, there is a chance deck-selected not being removed from class, so you see two tabs have deck-selected simultaneously and loss control to the tab you are switching to. In the meantime, no error is seen from browser console

Hope this info can help @mauro-balades

Could anyone try again on twilight once https://github.com/zen-browser/desktop/actions/runs/14693625488 finishes?

I've been failing to reproduce the issue with the latest twilight. I guess it works.
