When accessing a screen which has a text field selected by default (such as the world selection menu) using the "space" key, a space gets typed into that text field

The bug

When accessing any screen that has a text field selected by default (such as the singleplayer / world selection menu) using the space key, a space gets typed into the text field with which you can search for worlds. Thus, only worlds with a name containing a space are shown.

To reproduce

1. Open Minecraft

2. Press Tab, so that the Singleplayer button is highlighted

3. Press Space

4. ❌ A space got typed into the search field

5. Select Create new world

6. Press Space

7. ❌ A space got typed into the seed text field

If you press Enter instead, this issue does not happen.
