MS Teams share broken

Description of the issue:
teams.microsoft.com (WPA) is the site. login works. calls work. When in a call I try to share content using the share button. No matter what is selected, the share never starts. No error messages, the dialog closes as normal, there’s a flash on the target content to start sharing, but nothing occurs.

Exact URL of the website in question:

Did the issue present with default Shields settings? (yes/no)
Yes

Does the site function as expected when Shields are turned off?
No

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
No

Does the site work as expected when using Chrome?
Yes

Brave version (check About Brave):
Version 1.77.101 Chromium: 135.0.7049.115 (Official Build) (64-bit)

It’s fixed with an uninstall and re-install of the browser. The install contained an update to Version 1.78.94 Chromium: 136.0.7103.60 (Official Build) (64-bit)

Linux here, using v1.78.97 the web ms teams is still broken, no way to share yet.
