Still reproducing in 4.0.3.
It took me a long time to get it to repro: I tried changing my account settings > display > language to various values, as well as System Console settings to various config options.
Right now it's reproducing for me consistently with
All config.json settings set to defaults
Account Settings > Display > Language set to "Deutsch"
Reproduces in incognito mode.
Reproduces across browsers (on Win10).
Sometimes if I refresh the browser repeatedly, the page finally loads. But doesn't always work.
One person reported the issue reproducing first in MM 3.10.2. So not sure if it could be related to either of these two commits
