Firefox extension causes website to not load correctly

[sourworm]

Steps To Reproduce

In Firefox with the Bitwarden extension enabled and signed into account go to https://www.hunting.pa.gov/bof/huntmap/index.html edit: Opening the site in a new background tab does not cause the issue

Expected Result

The webpage should load and show an interactable map centered on Pennsylvania with a sidebar down the right side with various buttons and a top bar with title and links.

Actual Result

The site loads incorrectly without the map and only the sidebar and top bar are shown but the sidebar is on the left.

What loads in Firefox with the Bitwarden extension

Additional Context

I tried removing site data/cookies, loading the site in a private window, and disabling all other extensions but the issue always persisted if the Bitwarden extension was enabled. Disabling or even signing out (not just locking) of the extension made the website work again for me and then enabling or signing back in caused it to break again. The site does work correctly in Chrome with the Bitwarden extension enabled and signed into my account.

Just noticed that when I opened the link in my comment in a new background tab it does not have the issue and loads correctly with the Bitwarden extension enabled. If I enable the Firefox setting "When you open a link, image or media in a new tab, switch to it immediately" and then open the link in a new tab Firefox switches to that new tab immediately as expected and then the website does not load correctly again.
