Links: Undo doesn’t work for links that open in a new tab.

[thehenrybyrd]

Expected:
After adding any link, tapping “Undo” would undo the addition of the link.

Actual:
After adding a link which is set to “open in a new tap”, the Undo button does nothing and Redo button is greyed out.

Works in Paragraph, Header, List, Quote blocks.

To reproduce:

1. Create a new post
2. Add a paragraph block, type some text.
3. Add a link and set it to “Open in a new tab”.
4. Tap Undo and find it does nothing.

Tested on iPhone SE, (iOS 12.2) running WPiOS 12.7

This seems related to #1161, especially if that one is about state not being set correctly.

Closed #2495 as a duplicate and adding some additional notes from that issue. /hat tip @mchowning

Observe that no matter how many times you slowly tap the undo button, the link remains. If you tap the undo button a bunch of times very quickly, however, it is possible to remove the link.

Additional context
I wonder if there might be some connection between this and #2091

Tested and confirmed undo now works as expected in this scenario, I believe it was fixed as part of WordPress/gutenberg#50460.
