v2.5.308 breaks text rendering for draw.io diagrams

[tribut]

After Upgrading from 2.5.307 to 2.5.308, we noticed text in diagrams was no longer rendering.

Before update (v2.5.307):

After update (v2.5.308):

To reproduce:

1. Create a diagram with some text on a markdown page
2. Notice that neither the wiki.js preview nor the saved page show any text
3. Downgrade to v2.5.307
4. Open and save the diagram again
5. The text reappears

You can disable HTML Sanitization under Admin > Rendering > HTML > Security as a workaround.

The dompurify module was updated to the latest version which most likely has new rules that conflicts with draw.io.

We are having the same issue. The Workaround for disabling of HTML Sanitization worked. But text from a diagramm still does still not show in editor mode.

Same here, no solution/workaround for us, since this will break the editor view for the Users

Another workaround, restore a backup from before v2.5.308, copy the diagram source, and then replace the real page's diagram. This is rendering correctly using markdown pages (haven't tried on other page types)

Creating new diagrams is still broken though.

This has been an issue for quite a while, on text objects if you untick 'formatted text' and tick 'convert labels to SVG' they do render OK

We having same issue, but reverting to v2.5.307 doesn't fix. Furthermore, when we edit a diagram, it breaks also background and colors, not only text.

Pre-edit on Wiki reverted to 2.5.307

Post-Edit

I noticed that the text doesn't disappera, its just white as the background, then if its inside an object it self-create a contrast.
