Ctrl-click doesn't work [in the table of contents of a .docx]

Using latest version of LO Writer: 25.8.4.2
Ctrl-click doesn’t work in the table of contents when I open an existing docx.
I can get it to work by updating the table of contents.
I have tried turning off the ctrl requirement - no change.
Also doesn’t work in safe mode.

Writer can edit DOCX document with some limitations because this is not its native format. DOCX requires a conversion when read and yet another one when saved. This conversion is only approximative because founding principles are different in both formats.

When you force TOC refresh, the TOC is reconstructed according to Writer rules. It is not guaranteed to survive if you save afterwards as DOCX.

Attach a sample document for experimentation.

A general golden rule, valid with any application: always work in native format.

I reinstalled 24.2.5.2 and there is no problem with ctrl-click and the TOC.
