Fill Generated Password can take over control of H5Viewer input

[Altirix]

Steps To Reproduce

This is gonna be tricky for someone to reproduce as this is a local BMC webpage.

1. Open MegaRAC SP-X BMC H5Viewer
2. Click on the shell
3. "Fill Generated Password" appears in top left.
4. using arrow keys down will work once but after that the context jumps to the bitwarden extension.
5. must use down arrow key then click back on the viewer each time.

Expected Result

• "Fill Generated Password" does not appear in top left.
• does not override controls from the viewer.
• has some way to blacklist the popup on certain pages

Actual Result

"Fill Generated Password" appears in top left and context jumps to the bitwarden popup when using down arrow

Issue Tracking Info

• I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Anything youd think would be useful for the investigation i can provide? a bit limited in terms of what i can offer, as it is a BMC remote management panel. so there is no remote link i can provide.

the specific motherboard of the server is Gigabyte mc12-le0 but possible anything with Megarac sp-x should have the remote control viewer that is affected. maybe others too, but its likely this is a weird way they are capturing inputs which is conflicting with bitwardens detection of password input fields.
