Copy and paste from pdf exported from OneNote

I have text lines that are indented in my OneNote document using the Tab key like this (I have to include it here as an image because, it complains about invalid HTML otherwise and removes all the indent tab characters):

When I export this to a PDF and then try and copy and paste from the PDF, then the results are out of order. It looks correct in the PDF but the pasted text looks like this:

<tag3>
Text line
</tag3>
<tag2>
</tag2>
<tag1>
</tag1>

If I don't indent with the Tab key and just use spaces to form the indention then everything stays in the correct order (although all of the indention spaces are removed).

Has anyone seen this before? If so, is there a way to make the regular indents work correctly? I am using OneNote 2016.
