Bug 40481 – Consider adding support for :first-letter and :first-line in SVG

• Status: RESOLVED
• Resolution: CONFIGURATION CHANGED
• Component: SVG

[Abhishek Arya]

There was no seperate implementation of :first-letter and :first-line for SVG, which is why we had crashes and incorrect layouts when those pseudo classes were used for text elements in SVG. As a result, we disabled them in security bug - https://bugs.webkit.org/show_bug.cgi?id=40031. Other browsers such as firefox, opera, (svg implementation batik) don't support it. However, after chatting with Dave, Maciej, we should consider writing these features.

:first-line doesn't make sense for texts in SVG. We don't have block level elements like paragraph in SVG. So :first-line would always be true on texts. Are there other application areas for this pseudo element?

[Abhishek Arya]

How about :first-letter, does that apply to SVG ?

Yea, I think so.

cut-copy-paste from 40031

In an SVG user agent that supports CSS style sheets, the following facilities from [CSS2] must be supported:
---------
    * CSS2's dynamic pseudo-classes :hover, :active and :focus and pseudo-classes :first-child, :visited, :link and :lang. The remaining CSS2 pseudo-classes, including those having to do with generated content, are not part of the SVG language definition. (Note: an SVG element gains focus when it is selected. See Text selection.)
---------

Is it part of SVG specification or a requirement ?

Adding myself to CC list.

I attached a test case. It does not seem to run in any browser.

Safari, Chrome, and Firefox all agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
