Site Editor - Undo Trap from navigation-links in block patterns.

[Addison-Stavlo]

Steps to reproduce the behavior

1. Visit the site editor on a valid test site.
2. Insert a "Header" from the sidebar inserter.
3. select "Create Header", choose a pattern and create.
4. press the "undo" button, notice nothing is undone.

An undo trap has been created, preventing the user from being able to use 'undo' to undo the template part creation action or any actions prior to it.

Important notes:

1. This does not happen if you select "start blank" instead of a starting pattern.
2. This does not happen in core Gutenberg.
3. After syncing the most recent Gutenberg trunk as of this morning to dotcom sandbox, the issue persists.
4. This did not happen on dotcom a few weeks back, when e2e tests were written for the template part tracking flows.
5. On trying to 'undo' it seems to trigger replaceInnerBlocks and editEntityRecord for the template part.
   Update:
   This only seems to happen when the pattern selected contains the navigation-link component. Try creating a Footer using a pattern without a navigation component and 'undo' should work as expected.

Can now reproduce on core if using a pattern containing navigation-links like so:

			<!-- wp:navigation {"orientation":"horizontal","itemsJustification":"center","align":"full","style":{"color":{"background":"#ececec"}}} -->
			<!-- wp:navigation-link {"label":"Home","url":"http:\/\/Home"} /-->

			<!-- wp:navigation-link {"label":"About","url":"http:\/\/About"} /-->

			<!-- wp:navigation-link {"label":"Contact","url":"http:\/\/Contact"} /-->
			<!-- /wp:navigation -->

Removing the navigation-link's from the pattern causes the undo to work as expected.

What I expected to happen

Undo to actually undo back to the placeholder:

What actually happened

undo does not work as expected as it is caught in an undo trap with the navigation-link components.
