MacOS Ventura - PWA closes whenever Brave closes and causes Brave to be opened when opening

Description of the issue:
I have installed a PWA from Whimsical.com, and it seems to be treated just like another tab. If I close Brave, the PWA is also closed. If I have 6 tabs open, I will be warned first “You have 7 tabs open”. When I open the PWA directly, it also opens Brave in another window.
This never used to happen (i.e I could open and close the PWA or Brave separately) but since updating to Ventura it happens. It does not happen in Chrome.

How can this issue be reproduced?

  1. Install a PWA
  2. Open and close it
  3. See Brave also open and close

Expected result:
PWA should function separately, without the need for a Brave browser window also open

Brave Version:
Version 1.45.123 Chromium: 107.0.5304.110 (Official Build) (arm64)

Additional Information:
This is also affecting someone else I know after upgrading to Ventura.
