Bug description:
In level editor, when writing in a text field, pressing "Windows" + "Space" to change the keyboard layout or language can make the game pan continuously as if holding middle click.

Additional info:

• The issue can be resolved by defocussing the game (by clicking in another screen or pressing Alt Tab) then returning to the game.
• The issue only occurs when the keyboard quick menu appears over the game (screenshot added).
• The quick menu only appears over the game when switching to a Keyboard Layout which is not localized to the country selected for your computer.

Repro rate: 100% (For me, occurs 100% of the time when repro steps are followed.)
Steps to reproduce:

1. If you do not have more than one keyboard layout add one through the language options (many tutorials on how to do this are available online).
2. Host a server in multiverse.
3. Open the server chat by clicking but text bubble in the lower right corner of the screen then click the text field as if you were going to write in it.
4. Click on the text field to rename the object then press "Windows" + "Space" until the keyboard quick menu appears over the game.
5. Notice that the game pans continuously as if you were holding middle click.
