Selection isn't passed with isTriggeredByYDoc

[johngodley]

When a UPDATE_BLOCKS_WITH_UNDO is triggered and isTriggeredByYDoc is present the selection isn't passed. This has the effect of resetting the selection status in the editor undo history, and when you travel to the point the focus is removed from the editor.

To reproduce:

• Start storybook 'with on load'
• Click on the end of the first line, press enter, and type a letter (a)
• Press undo
• Press undo. Focus has now been lost

Looking at the store actions. The selection is passed here:

However it isn't here:

I'm not sure why the number of blocks would be so different either
