Some Developer Tools settings don't persist in new tabs/windows

I’m trying to permanently disable a Dev Tools setting called “Enable CSS source maps”, but I have to do it every time I open a new tab or window. In other Chromium browsers, this setting persists.

How can this issue be reproduced?

  1. Open a tab
  2. Open Dev Tools
  3. Go to dev tools setting (gear icon top right)
  4. In Preferences, uncheck “Enable CSS source maps”
  5. Open a new tab, repeat steps, and notice that “Enable CSS source maps” is again checked

Expected result:
The setting should persist in all new tabs and windows, just like in Chrome and Edge.

Version 1.34.80 Chromium: 97.0.4692.71 (Official Build) (x86_64)

Additional information:
The preference “Allow scrolling past end of file” is also not persisting in new tabs or windows.
