@appden Thanks for this! Do you happen to have an example of the useBlocker issue you're fixing with the latest commit? I'm tempted to deal with that separately...

No prob! I made that commit because I originally neglected to run tests (doh) and saw several tests in use-blocker-test.tsx fail on CI that I presume would have blocked merging this in.

Ah ok if they were caused by these changes that makes sense. I'll try to do some deeper testing on this next week 👍
