Bug ID: 160593
Summary: SVG import: wrong calculation of tspan's dy using em
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium

dy in em's
The attached SVG has this markup:
<text x="5" y="20" style="font-size:16px;font-family:Liberation Sans">foo
<tspan x="5" dy="1.5em" style="font-size:0.5em">bar</tspan></text>
It sets the outer (text's) font-size to 16px, then in the inner tspan, it sets
the font-size to 0.5em, and dy to 1.5em. According to spec, the font-size value
of the tspan must be calculated as half of its inherited font-size (i.e., half
of 16px); and in all other places inside tspan (e.g., in the dy), the em must
refer to the current tspan's font-size (8px).
When opening the SVG in a browser (e.g., Chrome), the second line "bar" is
rendered much closer to the first line, than in Draw.
