Share extension gets stuck intermittently

[simonsturge]

Describe the bug If you share the same content multiple times the extension can sometimes get stuck (see video).

To Reproduce I've reproduced this by sharing to the app, going back to Safari and trying to share the same content again. It took quite a few attempts for me to reproduce this, perhaps sharing the same content 5 or 6 times, however, I've had users reporting this issue when sharing only for a second time.

Video is on Google drive as it's more than the 10mb limit

I also experienced that issue

it's a tricky bug to reproduce in a non-deterministic context. it's going to take a long time to solve.

v2.4.0 enhance threading to avoid race condition, maybe related to this issue.
