When adding a heading in the info macro, convert it to paragraph and convert it back to headings, there's a chance that all texts inside the macro will be converted as a headings. Please see the following screenshot which illustrates the behavior:

Based on the screenshot above, the "Paragraph 2" was converted to a heading and the same step is repeated again, and as a result the whole paragraph inside the macro is converted to a heading. This shouldn't be an expected behavior.

Steps to reproduce:

• Create a page
• Add the issue macro
• Put a few heading (eg: h2.) and paragraph inside the macro
• Move the cursor to one of the paragraph, change it to a heading
• Repeat the above step again

This behavior is reproducible in Confluence 4.1.9 and Confluence 5.1.2.
