--html doesnt work in web mode

[charlielinz]

Describe the bug

There is no any setting description about the html option in doc. Only said it "Store HTML report file". No any value example.
I tried "true", "html_prefix_like_csv" and it doesn't work. Can any one tell me what value should I set and where would be the report saved, and is there any way to customized the report html format?

Also face the same problem at version=2.5.0, just configuration the html = xxxx.html in the locust.conf file can not working, there is no xxx.html output ,but if wen running on the command line add the args '--headless --html=xxxx.html -t 10s ' will see the html been output.

Probably my fault, probably somewhere in main.py. Dont have time to fix it though, maybe you have time yourselves?

Automatic html report seems to work only in headless mode. I suppose it isn't a bug.
You need add 'headless' to your locust.conf or as a command line argument.

I think this is a bug, it should work in ”headful” as well.
