Not rendering on 2019.2

[WoLfulus]

For some reason I couldn't make it work on 2019.2 - nothing gets rendered (default import). Plus some errors pop (about file location) if I try to move the the folder to a subdirectory.

Ideas?

It looks like Unity have changed how TextAssets work in 2019 - either intentionally or this is a bug.

For example, if I create an empty project and add a bunch of different text files (txt, json and md) then the default inspector also doesn't render anything either. I would have at least had a basic preview in 2018. Scripts appear ok but they are a different asset type IIRC.

The markdown viewer implements a CustomEditor for a TextAsset, which seems to be picked up correctly but doesn't call OnInspectorGUI() as expected. It's called on input events but not it appears on Layout and Render, suggesting a bug to me - or at least a half-baked behaviour change.

This might require some input from Unity and further investigation

Almost certainly this bug in 2019.2 ...

Suggest you also login and upvote it, see if that gets unity's attention :)

Apparently there is a fix coming in 2020.1, however I've checked in a workaround for the bug in 2019.2.
