alignment-baseline attribute ignored

[Matt]

As per the title, Inkscape appears to ignore this attribute on <text> elements.

Version info:
Inkscape 0.92.2 5c3e80d, 2017-08-06
macOS Mojave 10.14 (18A391)
MacBook Pro 2018

MCVE:
<?xml version="1.0" encoding="utf-8"?>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="0 0 200 200">
  <style>text { font: bold 180px sans-serif; }</style>
  <text x="100" y="100" text-anchor="middle" alignment-baseline="central">2</text>
</svg>

Correct output:
Digit 2 centered in 200px square.

Actual output:
Horizontally centered, but vertically not.

We do not support 'alignment-baseline'. We do support 'dominant-baseline' and 'baseline-shift'.
