Opera cannot submit many form fields

  So, the other day I made HTML form with a couple of <input> elements
in a table, made a couple of changes to their values and tried to submit
the form. Opera v11.52 froze, consuming all processing power on one core
for over two hours, and then I killed the process, over ten minutes of
my time lost. Easy to reproduce, just make a form with 5000 or so input
elements and a submit button, hit submit, and Opera should freeze for a
good while. The time seems to be related to the number of elements, not
just the form controls, in the form, or something like that, in my case
I used fewer controls, but being inside a table there were many more e-
lements inside the form.

I then used Firefox to make the same edits in the form, submitting that
was instantaneous.

Some days later I did something similar with smaller forms, which worked
very well in Opera, until I came across a larger form again and ... lost
another ten minutes to the same problem.

Perhaps the counting should really start with "fool me twice".
