Description:
Since Inkscape 0.92 released, more CSS3 properties become available in SVG.
http://wiki.inkscape.org/wiki/index.php/Release_notes/0.92

Yep, let's set to NEW
Comment 2 Volga 2017-11-18 03:26:25 UTC
We also need to improve our HTML founctionality in LibreOffice, then make HTML and SVG backends share some supports for CSS3 properties.
Comment 3 Thomas Lendo 2017-11-26 14:07:53 UTC
Is this a kind of meta bug for CSS3 properties or is it for developers sufficient to have such general bug instead of a list of missing properties they can work on?

Ok, let's whirl this past Volga one more time.

In http://wiki.inkscape.org/wiki/index.php/Release_notes/0.92#SVG_and_CSS we can see CSS3 stuff not related to SVG 2:
- The new CSS 3 'mix-blend-mode' and 'isolation' properties are implemented, allowing setting the blend mode between objects without using filters. (This does not mention SVG version. Is it SVG 2 and thus should be left out?)
- The SVG 1.1 'text-decoration' property is now rendered (underlines, strike through, etc.). CSS 3 'text-decoration' properties are also rendered.

So Volga, can you investigate, if the mix-blend-mode and isolation properties are for SVG 2 or older? And test CSS 3 'text-decoration' in an SVG, importing to LibreOffice.

It may be that we will only make this for text-decoration.

SVG 2 draft does not mentioned mix-blend-mode and isolation. However W3C draft "Compositing and Blending Level 1" defined the properties, both of them are applies to container elements, graphics elements and graphics referencing elements in SVG. And MDN document also showing an example of using mix-blend-mode property in an SVG element.
See: https://developer.mozilla.org/en-US/docs/Web/CSS/mix-blend-mode

Ok, changing this to be about text-decoration and I will create new ones for 'mix-blend-mode' and 'isolation'.
