[Ahmad Saleem]

Fixed in Blink by - https://src.chromium.org/viewvc/blink?view=revision&revision=189707

WebKit Source - https://github.com/WebKit/WebKit/blob/1c560f2f0a48c96b3c68110cc2e4a8a44a1aa9ae/Source/WebCore/svg/SVGTextContentElement.h#L109

Change from "SVGLengthMode::Other" to "SVGLengthMode::Width".

I am not sure if it is reproducible on production anymore, it might not since this commit got rid of issue of mismatch in two places here of this function "lengthModeForAnimatedLengthAttribute":

I am not able to reproduce this using Debug MiniBrowser build based of WebKit 260676@main.

Marking this as “RESOLVED CONFIGURATION CHANGED”. Please reopen, if it is reproducible. Thanks!
