Several second delay before "desktop site" set on new tab

Description of the issue:

Browser is configured for “Prefer desktop version of sites”.

When launching a new tab, the “Desktop site” setting is unchecked

Wait about five seconds later, and with no further action check again, and now it is checked.

How can this issue be reproduced?

  1. Launch Brave mobile browser on Android.
  2. Settings -> Site settings -> Desktop mode -> confirm: Prefer desktop version of sites
  3. Close out settings
  4. Press + at top left for new tab.
  5. Very quickly (within a second or two) press … at top right for menu.

  9. Try again: press + at top left for new tab.
  10. This time, wait five seconds, then press … at top right for menu.
  11. Observe that “desktop site” is now checked. (THIS IS CORRECT)
  12. Browse to a page and observe that the desktop version is requested.
