Select mode: If text is selected when entering, you can't select other blocks

[jasmussen]

Description

If you've first selected text, then press Escape to enter select mode, you can't select other blocks. When you try, focus goes back to the block with the selected text.

Step-by-step reproduction instructions

1. Go to the site editor
2. Select some text in a block, can be a heading.
3. Press Esc to enter select mode
4. Try to click another block.

Focus moves back to the block that has selected text. I would expect the selection to disappear and the new block be selected.

I wonder if this has the same cause as my issue #58788.
