Description

Affected Version is (at least) T5.4-beta-6. I have a simple form that is submitted via linksubmit:

<t:form>
<t:linksubmit>submit</t:linksubmit>
</t:form>

On Internet explorer the form is submitted twice. This also causes a race condition so it is not 100% reproducible (but ~80%) and sometimes submits the form once with and once without t:formdata (rare case).

We tracked it down to:

if (form.trigger("submit"))

{ form.element.submit(); }

form.trigger("submit") submits the form the first time, form.element.submit() the second time.
