I see the same problem with Firefox (Nightly) on macOS. On Linux, the text does appear in the PDF, but the scaling is bad (so that a bunch of the content is cut off).

Regression range (on macOS):
https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=59fa65e9da080d96cf90d9c99a458372b8d58b4d&tochange=321d39a496831919d454ecac43c322fa16c87ad5

That suggests this came from the gfx.cairo_quartz_cg_layer.enabled pref-tweak in bug 1789482. And indeed, if I toggle that pref to false, then the issue goes away.

--> calling this a regression from bug 1789482.

...though really that means this is a regression from bug 1772225 (which just went away for a bit via bug 1779202 which put the behavior behind the aforementioned about:config pref and set it to false; and then this came back when we changed that pref back to true in bug 1789482).

[Daniel Holbert [:dholbert]]

(confirmed that older regression range with a more narrowly targeted mozregression run, which yielded https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=102a953cbf862aba9ed0804504c32a4a9ed6ece7&tochange=5563ec0537500a2ac4a38aa9271452b851a0c3ab , which does implicate bug 1772225.)

Thanks for the testing, Daniel -- it's pretty clear the CGLayer backend must be failing in some way on this file.

(Though even with the pref disabled, the output isn't great, as the content doesn't correctly fit the page and significant amounts of text are clipped. But at least that's the same on other platforms... presumably something about page size/viewport/etc.)
