Look in Preferences > Advanced > URL Bar Options. There is an option titled disableTitleMode, which is the localization variable name. In English, the localized text should be Always show the URL bar (source). As far as I can tell, this only happens with English. I tried Spanish and French, and it looks fine.
Actual result:
There is an option titled disableTitleMode.

Expected result:
The option should be titled Always show the URL bar.
Reproduces how often:
Always, if using English.
