Bibisect warning: bug 133767

Not sure if this can be bibisected and my good comment being of any value here -> see bug 133767 This is *not* a regression. In the range between 3b03604d1bb48fc1c1337307d0ba259dca9fbf1e and its correct revert in 02a5cbb9814dc224114dfbf3bc0b6c53658450c9, trying to export to EPUB actually saved an ODT. That code made incorrect selection to be returned to the calling code. So the fast operation and progress bar were artifacts of using another export filter, which both operates faster and shows the bar.
@Noel, Adding you're the perf magician. Note: a major downside: Windows only. So not sure if you the tooling present for that..
Dear Telesto, To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

We'd really appreciate your help in getting confirmation that the bug is still present. If you have time, please do the following: Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/ If the bug is present, please leave a comment that includes the information from Help - About LibreOffice. If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.
