 While typing in a block / paragraph, the cursor jumps to the ''beginning''
 of the paragraph. It happens while autosaving or language-correction. I
 testet Firefox 63, Edge and Chromium (all Windows 10). All WordPress-
 plugins were disabled, alls browser-plugins disabled. No mouse-movement at
 this moment, no keybord-buttons pressed.

 This problem happens since the 5.0 update.

 Video of the problem: [https://youtu.be/yJ2qSLq9hMs]

 In the video: I type some text and wait. While waiting the cursor jumps to
 the start of the paragraph. If I go on writing, the text is written at the
 beginning.
