Save continually blinks, breaks if on bad wifi.

[programmin]

If you save draft while internet is disconnected or flaky, it just continues blinking the saving, and will now allow publishing or actually saving draft again when network is working again.

Steps to reproduce -

• Save draft in Gutenberg editor with flaky internet connection.
• Connect, reopen laptop when on good wifi.
• Note that there is no way to save the post now.

Firefox console shows -
Yoast SEO and readability analysis: An error occurred during the building of the tree structure used for some assessments.

TypeError: e.children is undefined 65 analysis-1200.min.js:21:80480
TypeError: NetworkError when attempting to fetch resource.
uncaught exception: Object

There is now no way to save, I must go and read the current draft and go copy-paste all the blocks. Frustrating.

@youknowriad when you have a chance :) Does this still happen after the introduction of the "sessionStorage autosave mechanism" in the block editor?

I've never seen this issue personally but worth moving this ticket to a Gutenberg issue for better investigations.
