Hi Team,

I am unable to find the rationale for the following rule and understand why iOS need it since it does not exist for desktop and also not any other browser.

WebKit Source: https://github.com/WebKit/WebKit/blob/b5e4644abe94ff8a2991e7a9ceec14e2df43b6f7/Source/WebCore/css/svg.css#L64

It was added by this commit in 2014: https://github.com/WebKit/WebKit/commit/4c7785360b6851a86bab1caf0bde837b13e0a45f

and with just this comment in change log without any further explanation:

* css/svg.css: Added iOS-specific CSS styles.
(text, tspan, tref):

________

I think it also causes issue in one specific test failing on ios-wk2 when in the past, I tried to merge Blink patch to account for 'zoom' for SVG Text.

If there is valid reason than I think adding bit comment would help or else we should explore to get rid of it.

CCing - @Simon - since he reviewed the commit, which added this.

Thanks!
