Build configuration popup: Close it only by pressing the X

Description of the feature request

The damn popup where we can enter information for a custom build also close itself because I miss click outside or juste release click. It drive me crazy.

Please, close the popup only when we press the X.

Use case / for what or how I would use it

Hi Maxilapo,

This should be fixed now for release click, thanks for the report

Best
