Not a recent regression. At least, I can reproduce on Firefox38.0esr...

Regression window:

Setting network.http.spdy.enabled.deps = false seems to fix the issue on Nightly74.0a1( 20200209092928) and 38.0esr.

Has Regression Range: --- → yes

This is probably a server problem. It is not handling our priority tree correctly. Anyway we are going to look into priorities anyway.

Priority: -- → P3
Whiteboard: [necko-triaged]

The site changed to use HTTP/1.1 from HTTP/2 for the root document.
