<!-- Please report new issues at https://inkscape.org/report; this tracker is for staff-confirmed issues only. See our full bug reporting guidelines at https://inkscape.org/contribute/report-bugs/ --> #### Steps to reproduce: <!-- Describe what you did (step-by-step) so we can reproduce: -->  Have a shape with custom XML attributes. Use the inset function on it. #### What happened? The inset function destroys the custom XML data. ... #### What should have happened? The inset function should preserve the custom XML data. ... #### Inkscape Version and Operating System: Inkscape 1.2.2 (inkscape@b0a8486541ac36327488da641d58a86bee2f07ad, 2022-12-01) Windows 11 <!-- Example file: Attach a sample file (or files) highlighting the issue, if appropriate. --> I can understand the combine feature altering XML data, but the inset feature only changes the shape data. The simplification function doesn't alter the XML, so would it be possible to do that for the inset?
