Not sure if it's connected to the recently closed issue https://github.com/ckeditor/ckeditor5-engine/issues/1155 and PR: ckeditor/ckeditor5-engine#1201

I changed the timeout to 1000ms and it didn't help. For some reason, the model selection is incorrect.

Similar scenario (caused, most likely, by the same issue):

1. Refresh the page (so everything is lemon fresh).
2. Click in the content.
3. The selection appears there, but it's moved to another location after <1s.

This happens, most likely, due to the focus event being fired with a delay. The mechanism was described here: ckeditor/ckeditor5-engine#1442.
