There is an increased waiting time with the thousands of pending bugs on Gutenberg. My latest one has been pending since November and no end in sight. I feel if you are pushing a completely new editor to the system, handling these issues should be high priority.

@ChristineCooper there's only so many people to work on things

that specific one is most likely a REST API bug

I need something to complain about to feel good about myself. =)

I traced the source of that in GB down to the data package getEntity method

it doesn't provide a means of specifying the context, so I believe the bug is in the REST API

specifically that the author should have access but is unable to read because of the editor context

perhaps the solution is not to specify that context when retrieving media via GET? Or a change in the API handler

eitherway that issue should impact more than just the featured image

the latest posts block UI should be impacted too from my reckoning

and there may be a PHP based solution

as well as an easy way to write a test for it

Yes I figured as much, thanks for replying there. Last time I checked (it's been a while), it does indeed affect other areas as well. I believe something within the media library box. I need to test this out again.

if you can demonstrate it's a wider-ranging issue than just the featured image it'll probably get more attention

raise issues for every instance and then tie them all together in a new ticket for the root cause

I suspect though, it'll require a WP release to fix though

IDK if my eyes are getting bad, there was a chrome update or what but the code highlighter reds are off-putting...

They need to be a few hexes darker IMO.
