Steps to reproduce

1. Go to a board (instance: Bulldog)
2. Click an issue X, so the 'detail view' pops up on the right
3. Write a comment, don't save it
4. Right-click an issue Y on the board, e.g. to copy issue URL

Expected result

Issue X is in detail view, comment is still in 'edit' mode

Actual result

Issue Y is in detail mode, comment is lost

This is particularly annoying, as:

• Description or any other field in 'detail mode' is 'inline' editable and saved upon navigating away
• Any other comment or page where you navigate away from something you're editing has a 'Are you sure you want to navigate away? You'll lose your things'
• Right-click should not trigger another issue to get focused/become detail-moded

NB this was on version 7.8.0-RELEASE-BDOG-2815, but had to select an affected version below (so chose 7.7.0 Server)
