1145969 - [HTML5] successive tags of type command get nested

Status: RESOLVED INVALID

(Core :: DOM: HTML Parser, defect, P5)

Description

[Peter Möller]

Attachment: little code example menu.html

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 2015022000

Steps to reproduce:

FF 36.0
OS: OpenSUSE 13.1 64bit

played around with html5 tags and used 3 tags of type menu 
successively, each with closing "/".


Actual results:

FF will nest them, also seen with firebug


Expected results:

There should have been 3 menu tags next to each other, especially, since i added the display: block attribute.

Of course, I'm an early adapter, but this is a structural error ;-)

sorry not the menu tag gets nested, but the command tag

Comment 2

Some hints:
- using a closing command tag instead will solve the problem
- the command tags have no height, I must enforce it with height attribute
- using text between opening and closing command tag will give height

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority.

If you have reason to believe this is wrong (especially for the severity), please write a comment and ni :jstutte.

just walking through my old bugs to see, what might be able to get state "closed".
This one is not a big deal and needs no big priority. Only nasty thing is: "After" this tags the parser structure is broken until another closing tag helps to synchronize parsing again.
In order to see it in a detailed way I will add a screenshot of the parsers "red colored" characters, that shows the structure problem best, seen with ff 87.0b7

Ok, gave a try to the docs, result="The <command> element has now been dropped from the HTML5 specification"
will close this one
