I used the Insert HTML tool to insert an <audio> tag to the Body. Then I reopened the Insert HTML tool to add
and then clicked OK. Then I hit the Publish button. When I Previewed the page, and then used FireBug to look at the <audio> tag on the site, the "type" attribute, that I added, was gone!
So, I used "View Page Source" to look at the actual code, and it was missing from there, too! So I went back to VSD and re-opened the Insert HTML object and it still shows the "type" attribute that I added.
So, to be absolutely sure that I was looking at the correct site, I went to the Publish menu and clicked on "Open Published Website" and did a "View Page Source" on that, and STILL no "type" attribute!
Any ideas on what the heck is going on?
