Compose Key not fully working

Description

I’m using a US keyboard and sometime writing in german. To do so I use the Compose-Key to write letters such as ü, ö. In mailspring there is a weird behavior were when the Compose-Key is pressed (Right-Ctrl in my case) I can start input the sequence (Right-CTRL → “ →o) but the time I have is super short and random sometimes and this makes it very frustrating to use. In no other software (e.g Firefox) this behavior happens

To Reproduce…

Steps to reproduce the behavior:

  1. Press Right-CTRL and try to do the sequence

Expected Behavior

More time to input the sequence (Right-CTRL → “ →o)
