commit 20d5851fb7ad2d03e499f7f59f022a771cee9a93
Author: Jean-Marc Lasgouttes <[email protected]>
Date: Mon Jul 25 22:13:35 2022 +0200
Regenerate equations previews when their numbering changes.
Time will tell whether this is too expensive (because most equations
after this on will change too, unless equations are numbered by
section).
Related to bug #11535.
