This works for me with a current FIrefox release (61.x) and also with Firefox nightly (63).
Do you see this issue only with the Firefox beta ?
In case you have extensions installed, does it make a difference if you start Firefox without extensions ?

I've just tested with the procedure to disable addons (went into safe mode). 

The diagram at the top of the page is still not rendered correctly. More specifically the cloud of colored dots is missing.

I can confirm the reported bug in Firefox62 Beta but it works in Firefox61 and in the Firefox63 nightly.

Matt, how easily could we create a backportable patch for this issue?

Should be really easy, I'll pull beta and try rebase now.

Looks like they apply as-is, made the uplift request.
