Internals Reference - some grob links haywire

In the current docs for v2.25.23, the link
http://lilypond.org/doc/v2.25/Documentation/internals/all-layout-objects
brings me to section 3.1  i.e Backend > All layout objects

If I hover over the '3.1.19 Beam' link, Firefox 115.19.0esr shows me
http://lilypond.org/doc/v2.25/Documentation/internals/beam

If I then click on the '3.1.19 Beam' link, Firefox doesn't take me to
http://lilypond.org/doc/v2.25/Documentation/internals/beam
but rather to
http://lilypond.org/doc/v2.25/Documentation/internals/internal-backend-properties.html#beam 

which is the entry for 'beam' in section 3.4


The same error at the bottom of section 3.2.15 breaks the link loop.


This seems to happen for only the following grobs:
Beam Dots Flag Footnote InstrumentName Rest Slur Stem Tie

The docs for v2.24.4 don't have this problem.


Cheers,
Robin
