Bug description

When using Preferred Applications tool to change Web section to a new browser (Brave Flatpak 1.88.132), it changes the Cinammon interactions opening web pages in Brave, but doesn't change the behavior of the default open command run from the terminal.
open /path/to/example.html uses xdg-mime which was showing Firefox (xdg-mime query default text/html -> firefox.desktop) which it should have been pointing to the brave instance.

Workaround

Manually setting it with xdg-mime default com.brave.Browser.desktop text/html works

Steps to reproduce

1. Install LinuxMint
2. Install Brave flatpak
3. Open Preferred Applications
4. Change web browser preference to Brave
5. Open terminal and run xdg-mime query default text/html
6. Observe - Firefox is still the default

Alternatively

1. Install Brave flatpak
2. Set Preferred browser (in Preferred Applications) to firefox
3. Set xdg-mime default firefox.desktop text/html to change it to firefox
4. Set Preferred browser to Brave
5. Open terminal and run xdg-mime query default text/html
6. Observe - Firefox is still the default

Expected behavior

Changing the default browser should change it for all setup mime systems.

Additional information

gio mime text/html has com.brave.Browser.desktop at the top as expected
