Unable to perform any actions when copilot tab is opened

When the copilot tab is opened, I cannot click anything on the web page, or chat with copilot. The only thing that works is the toolbar at the top of the copilot (chat compose...).

After I close it, I am able to access the web page again. I have reported this via feedback.

I had this issue in beta 119. Then I tried to download dev 120 but got the same problem
