[Support System] Add link can't be cancelled by clicking next to link popin

Hi,
When composing a message in the support ticket, the add link option can not be cancelled by clicking outside the popin. Please see a video of the issue here: https://www.screencast.com/t/FLx7jRfNvz

No need for a fix right now, just wanted to report it for a future release of the app.

Thanks,
Syl
