I'm seeing this assertion on lots of SVG tests since a while, haven't found yet to bisect it.... :(
Not sure since when this is happening...

[Ahmad Saleem]

We have it as [ImageOnly Failure] on wk2 mac Ventura:

https://searchfox.org/wubkat/source/LayoutTests/platform/mac-ventura-wk2-lbse-text/TestExpectations#341

For Layer Based SVG.

While results on 'results.webkit.org' seems to show it running fine across other platforms.

Marking this as 'RESOLVED WONTFIX' since LBSE is still ongoing work and @Nikolas will fix it in future any way and this old bug does not add much.

@ap - anything else to add this bug or my conclusion is fine?
