doFetchModBlockedList is blocking the ui thread.

Duplicate data in doFetchModBlockedList::blockListsPerChannel to about 1000. The tab is dead when function hits, about 4s after reload.

  • Yield occasionally using the setTimeout method.

  • Doing a chunk size of 1 for now so we don't have to yield the inner loop as well (seems good enough). This is just based on a relatively large blocklist size.

  • Can't do await in a callback, so must change the forEach to a for.
