Bug 163552 – Using <form> in <template> causes following <form> to get swallowed

• Status: RESOLVED
• Resolution: FIXED
• Component: DOM

[Dennis Morhardt]

If your using <form> in a <template>, every following <form> will be eaten up and only contains will be rendered.

See http://jsbin.com/buwuteripu/edit?html,output for a demo.

It seems to only eat the following form. Not every following form.

See http://jsbin.com/razakunaca/edit?html,output for a (updated) demo.

Confirmed, Same goes for TP.
just recently registerd to report this issue. But i found this.

thanks maxime for the suggestion, going to put a empty form right before my following form so it can eat the first one instead

Looks like an HTML parser bug.

WIP Patch

From spec:
Insert an HTML element for the token, and, if there is no template element on the stack of open elements, set the form element pointer to point to the element created.

It looks like we were setting the form element pointer even when there was a template element on the stack of open elements.
