*Tiddlywiki 5.3.3 (recently upgraded) over nodejs
*Tiddlers upgraded
*Case tested with Safari, Chrome and Firefox, all the same behaviour.
As you can see in the attached image when I open this tiddler for edit, with the preview window activated, the edit window is very small, actually almost not editable.
What is weird is that it happens only on this specific tiddler, others open ok (almost I didn’t check all my 600+ others…).
I launched a new nodejs test tiddlywiki, vanilla (no plugins or customization) and imported the OSX (MacOS) tiddler but this isn’t a fix, I still have this problem.
That should do it. You will probably want to try to remember to delete this when you upgrade to a version that has the fix. It’s not so much that it will be harmful, but it will certainly be unnecessary clutter.
Alternatively, since I tried this myself, you can download this link and drag the result to your wiki:
