Quoting a post that has a spurious [/quote] tag does not work correctly

Test.

Test.Still a test. Single quoted text

Text that should be quoted when this post is quoted.

Morning @DFranklin! We've released some additional changes that should resolve this, could you let me know if you're still experiencing the issue, please?
For context, we've released an update to the app that should stop quotes from nesting when replying from there, and another update to the website to strip out nested quotes when quoting a post, so I'd expect both sides of the issue to be handled now!

You still have an issue if quoting a post that has a spurious {\quote} tag. See posts 12 and 13 in this thread.
