We have a user who has created a couple of blocks on a page using the Mosaic Tabs macro, and is using Headers to create a Table of Contents. Above each Tab set, there is an H1, and each tab section uses an H2. The Table of Contents at the top of the page shows the hierarchy, and the top-level (H1) titles link to the appropriate place on the page, but the H2 header links (in the tabs) do not work. Is this a bug?
