Not offhand.  Again, it's been a while since I looked into this, but at 
the time this was being implemented in Gecko we carefully made the 
two-input-no-submit case not submit.  I thought that was for good 
reason, but reskimming the bugs now I can't find the reason.  It's been 
over 10 years, so the details are a bit hazy in my mind.  :(

https://bugzilla.mozilla.org/show_bug.cgi?id=22526 is the other bug that 
needs reading, but it doesn't help either.  I didn't look at the various 
(and somewhat numerous) duplicates of the various bugs involved...

I suppose we could try submitting the "more than one text input, no 
submit button" case and see what happens...
