valign not working on mglyph

Created by: wspilot

I am using an svg (also tried an .png) as mglyph and it has to align with the descender line of the preceding character. Whatever value or unit I use, the glyph stays on the base line. Ubuntu 19.10 Firefox 73.0.1 Chrome Version 80.0.3987.87 (Official Build) (64-bit) See attached html and svg file. Note: I had to rename the files toto .txt because .svg and .html are not accepted as type. Please remove the .txt extension. bugTest0.svg.txt bugtest0.html.txt
