Bug Description

When applying a cut on two objects in newest 0.92 Inkscape release, they move diagonally.

Here's a preview of the issue under Arch Linux 64-bits: https://vid.me/Aw4I

Please attach a test case (Inkscape SVG file(s), before and after applying the path operation) to the bug report to allow further investigation, thank you.

Oki. Test case zipped in the attachment.

This happens when using the preference setting for Clippaths and masks to not remove the clippath/mask object after applying (not the default), and the clipped object is within a transformed (layer) group or has itself a preserved transform attribute (e.g. a translate() command).

this change of behavior seems to have been exposed with the changes in r14130:

Note that in a short period prior to rev 14130 - from r14094 to r14129 - the retained original clippath was incorrectly clipped (with a copy of itself), but still correctly positioned. Revision 14130 did fix the "double-clipping" (the rectangle in the test case is no longer clipped), but introduced the offset due to present preserved transformations.
