Control: reassign -1 src:sphinx Control: retitle -1 sphinx breaks python3-breathe < 4.15 Control: tags -1 patch
This does not happen with breathe 4.19 (from experimental); this upstream report suggests it happens with breathe < 4.15.
https://github.com/sphinx-doc/sphinx/issues/7424 Hence, a fix for this is to increase the Breaks: version to 4.15 https://salsa.debian.org/python-team/modules/sphinx/-/blob/debian/master/debian/control#L67 and move python3-breathe from experimental to unstable before sphinx.
