Safari Plugin Rendering Some Webpages Unresponsive

Steps To Reproduce

I've encountered this on a handful of sites and given up or moved on, but I was able to finally diagnose it consistently on progressive.com.

Enable Bitwarden Safari Extension (2024.6.1)
Enter progressive.com in Safari address bar
{Website loads}
Click (maybe) any link on the page
- In my case, I noticed it when clicking the Log In link in the upper-right portion of the page.
Website becomes unresponsive, and there is not response to clicking any link on the page.

I've also confirmed that the final step above does not occur when the Bitwarden Safari extension is disabled.

Expected Result

Access the desired webpage upon clicking the link.

Actual Result

Web page becomes non-responsive. Also, hovering a link does not switch the cursor into "pointing hand" mode.
Additionally, reloading the page does not work. The tab must be closed and then navigate to the site again to repeat the behavior.

Screenshots or Videos

No response

Additional Context

Below is the console log from Safari's dev mode.

Another note is that the final error

[Error] TypeError: globalThis.requestIdleCallback is not a function. (In 'globalThis.requestIdleCallback(this.processMutations, { timeout: 500 })', 'globalThis.requestIdleCallback' is undefined)
(anonymous function) (bootstrap-autofill.js:369)

occurs upon clicking the link and repeats indefinitely at approximately 1k calls per second.

This does stop upon navigating to a different site.

Issue Tracking Info

[X] 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.
