text-overflow property is missing from attribute index

[SebastianZ]

The attribute index of SVG 2 is missing the text-overflow property.

Do any browsers support text-overflow as a presentation attribute?

In general, we had resolved not to add new presentation attributes unless there is a compat reason to do so.

If the example I created on the MDN documentation page is correct, then Firefox 67, Chrome 75, and Edge 44 do not support it.

Ok, so I assume that this one should be removed again then. (And I should remove the MDN page again.)

There's nothing to remove (yet). The entry in the text chapter describes how the CSS property (set with CSS) would apply to SVG text.

Of course, if no browser has implemented that, either, we may need to mark it as risk. But that will get bundled with changes to defer all SVG multi-line text functions to a future version of the spec. Even though text-overflow would be useful even without the other new properties, e.g., for text on a path.

Re MDN: Yes, remove it from the attributes section. It would be helpful to have information in the regular CSS text-overflow page, that it is defined to be valid on SVG, but support is poor.

Oh, yeah, I missed that. So then it's missing from the properties index. 😉

I've now tested the example given in the spec. in all three mentioned browsers and unfortunately they also do not support the property.
So I've filed a request for implementation in Gecko. For Chromium/Blink there was already one filed. If you test it in Safari and it also doesn't work there, I can also file an enhancement request in WebKit's bug tracker.

Off-topic for this issue, but is there some central place where all the ideas for a future SVG spec. and the features removed from SVG 2 are collected and discussed?

I removed the page again. As no tested browser currently supports the property and annotation 36 indicates that it's value seems to be controversial and therefore may be removed from the spec., I decided now not to document it for now and rather wait for whether it get's traction.

Ah, remembered it. That was https://www.w3.org/community/svgcg/. Just joined the group now.
