The TAB key no longer works in Brave browser

From today the ‘TAB’ key no longer works when I try to edit the card code, but this only happens in the Brave browser.
In fact, using Chrome and Edge I can easily use the key and edit the card code.
I have updated HA to the latest version.
Furthermore, using Brave the TAB button works on other sites, for example trying to modify the code on the site https://www.w3schools.com
I thought it was ‘Browser mod’… So I disabled it and restarted HA but it didn’t fix the problem.

Has this happened to any of you?
Does anyone have any idea how to fix this annoying problem?

Thanks

You should not be using tabs in YAML, only spaces.
