Thanks—yeah, that's fair. I'll see if I can create a reduced test case.

I did discover a couple additional things as I debugged further.

The first is that the amount of time the background script stays "alive" for is quite consistent—just under 8 minutes. After that, it dies/goes away.

I also discovered that by calling `runtime.sendMessage` on an interval from the content script, and sending an arbitrary response back from the background script, I can keep the background script alive. I recognize that's more of a workaround than an actual fix, but it does seem to work.

One final point of note: this issue seems similar to a pair of issues that have plagued Chrome for some time now:

- https://bugs.chromium.org/p/chromium/issues/detail?id=1271154
- https://bugs.chromium.org/p/chromium/issues/detail?id=1316588
