Confluence Source Code Editor Reinstates Parameters on Publish of Page

[Chris LaGambina]

I have iframes in a HTML macro and have been struggling with scrollbars for quite some time. After way too much time trying to figure it out, I find the source code:

<ac:structured-macro ac:macro-id="bca12819-7ce6-44aa-a55d-4f1f2d006db1" ac:name="html" ac:schema-version="1">
<ac:plain-text-body><![CDATA[<iframe src="omitted" width="100%" height="650" scrolling="auto"> </iframe>
]]></ac:plain-text-body>
</ac:structured-macro>

Specifically the ac:schema-version=1 is what is making my iframes have horizontal scrollbars. After removing this and publishing my page, no scrollbars!

Unfortunately I have found that  the Confluence Source Editor appears to automatically reinstate the missing macro-id and schema parameters.

Im no programmer, just trying to edit a confluence page I am building. Any help in trying to figure out a workaround or better way of doing this, please let me know.
