From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.9+) Gecko/20020318 BuildID: 2002031803 An embed tag with a hidden attribute displays a transparent box moving all content below it. An example of the tag is: <embed src="file.midi" hidden="true"> Reproducible: Always Steps to Reproduce: 1. View a page with a embed tag with the hidden atribute Actual Results: All the content is moved down below an invisible box that the embed tag created. Expected Results: The embed tag should not have rendered anything on the screen. The content should have been been moved up. See attachment of the test case.
The <embed> tag is not standard HTML, nor is the "hidden" attribute. Hiding it with CSS should be effective. Should probably be WONTFIX or INVALID.

Maybe this topic should be another bug, but on my computer the sound is not played. I always assumed that it was because a helper application on my computer was not set up correctly; but, if mozilla does not support the embed tag (and that is the reason why their is not music on the web page), then mozilla should ignore it and not display anything regardless of the fact that their is a hidden attribute or not. Am I understanding everything correctly?
I think <embed> may be necessary for IE; we may support it too, for compatibility. Try wrapping the <embed> tag in an <object> tag with the appropriate attributes: data="location of file" and type="MIME-type of file", and I think it should work. You are correct that the "hidden" attribute should not affect Mozilla's handling. I'm going to resolve this bug; the above solution should make the object invisible, anyway. Good luck!

Um... I'm sorry, but I disagree. Reopening. We _do_ handle the "hidden" attribute. We map it to "visibility:hidden" in CSS. Unfortunately, both IE and NS4 act more like "height:0; width:0" (or maybe even "display:none") in response to that attribute. This should be fixed, imo.

Looks like a ObjectFrame - plugin issue. Reassigning to peterl.

Nope, this is broken :( Patch in bug 136456 will fix this. Note: We don't map it to visibility as according to CSS spec this leaves space in layout while the hidden attribute acts more like display:none in 4.x. We can't use display:none at this time because plugins are tied to frames. Does anyone know if I.E. or 4.x support the hidden attribute on applet tags? *** This bug has been marked as a duplicate of 136456 ***
