I am multi-layout language keyboard user. During editing text in javascript textbox (such as editing sheet name in Google sheets) in Firefox, when I pressed win-space to switch language: 1. expected behavior: I can continue editing my text with keyboard layout switched What happened instead: 1. keyboard layout is switched 2. a space character is added the to the text. and got popped out of text editing mode Is there anything I can do about this issue? Please help. Thank you
