Jryans: most of the patch should be simple enough (minor eslint changes in tests, mostly). But here are some comments about the trickier parts:

- The testActor registration and access functions aren't being exported in a common way, and so eslint can't find them automatically, so I've just added a /* globals */ comment for them.
- inspector-search.js uses a fallthrough in a switch/case that eslint doesn't like, so I ended up just disabling eslint for that line.
- inspector-panel.js is a long file that had many lines longer than 80 chars. Instead of wrapping them all and ending up with potentially weird formatting, I wanted to experiment with a 100 chars long lines, which is why there's a comment for this at the top of the file. I'd like us to have the same config for this rule everywhere in the codebase, but at the same time, this enables making files eslint-clean pretty easily. I once started to remove eslint errors in some of devtools/server/actors file, and all I was doing was wrapping lines at weird places. Just changing 80 to 100 in those cases helps a lot. And I don't think people mind too much what's the actual value, just that there is one.
- I completely rewrote browser_inspector_search-suggests-ids-and-classes.js because it looked weird and it made it easier to fix eslint errors that way. It dates from before we used tasks so much in tests and so it just didn't fit in with the other tests. The functionality is the same.

The walker methods called here are RDP methods, right?  I would think they return promises, so this should return `promise.resolve()` or something equivalent so there is a promise returned by all paths.

Should be resolved promise.

Should this function have a return value at all?  It's only bound as a event handler it seems...

::: devtools/client/inspector/test/browser_inspector_menu-01-sensitivity.js:284

I am not a big fan of this rule that blocks inline comments...  Just an aside. :)

You're right. I have corrected this. Although in this case it made no difference because nothing was using this return value.
