In recent versions of Confluence (eg. v7.10) when an indent is added to text it applies 40px width value intervals. In older version of (eg. v7.4) it does the indentation 30px intervals. The change/difference in the newer Confluence versions means that our Exporter apps do not preserve the indentation provided by the editor due to the logic checking if the indent is a multiple of 30px.
Steps to reproduce
Create a page
Add some text content
Apply the indent option (once) from the toolbar
Expected result: The indentation is preserved in the export
Actual result: The indentation is NOT preserved in the export
