Add a close button when leaving spaces

[frakic]

Your use case

What would you like to do?

I think it would be great if we added an X button to the top right corner of the warning that appears when a user tries to leave a space.

Why would you like to do it?

I wanted to cancel leaving a space so I intuitively reached for the top right corner, only to realise that there's nothing there.

Have you considered any alternatives?

The warning can actually be closed by swiping from top to bottom but I feel like there's enough room for a button.
