Confluence Indent not preserved in generated export

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
