Block Template Warning Missing in 5.2

[benplum]

Describe the bug
Prior to 5.2, a warning was displayed when a post's current blocks did not match the defined block template. The warning contained an option to reset the post to match the block template.

To reproduce
Steps to reproduce the behavior:

1. Edit or add a block template to a post type.
2. Edit an existing post of that type.
3. See that the warning is missing.

Expected behavior
A warning should be displayed, with an option for the user to reset the block template.

I know there was an issue where the warning would also display when the post type's block template contained a locked set of outer blocks, and unlocked set of inner blocks. If I had to choose one, I'd rather have an ever-present warning than no way to reset the block template.

I've attempted a work around using:

wp.data.dispatch('core/editor').resetBlocks([]);
wp.data.dispatch('core/editor').insertBlocks( ... );

However this fails if template_lock is on. (Also, how should wp.data.dispatch( 'core/editor' ).synchronizeTemplate(); work?)

Thanks, the warning is back. Hope #11681 get some attention soon.
