forgot to add reproduction steps:
1. run a bun script with --inspect
2. open link in firefox with standard security mode
3. see above error

There is no file in Web Inspector matching this pattern: `manifest-yr1khc1r.js`
Is this a bug in a forked project? Sounds like it from the steps to reproduce:

> 1. run a bun script with --inspect
> 2. open link in firefox with standard security mode

The function `isInsertionCaretInside` is an extension to the `Element` prototype defined here: https://github.com/WebKit/WebKit/blob/main/Source/WebInspectorUI/UserInterface/Base/Utilities.js#L505
Perhaps the file is missing from the project.

I don't think this actionable here.
