I cannot reproduce the issue. I attached the saved page in the zip file below.

Test again, close HTTPS Only Mode totally fix this issue.
I close HTTPS Only Mode temporary for this site so this issue happened.

[gildas-lormeau]

Pardon my ignorance but how can I "close HTTPS Only Mode"?

[ivysrono]

Close -> fix
Close temporary -> issue

[gildas-lormeau]

Well, this website does not support HTTPS...

I'm not sure why this issue only happens while Turn Off Temporarily, not Turn Off.
