I've been asked to resolve an issue on an EE 2.7.3 site with Structure 3.3.14
I didn't build this site and will be recommending an upgrade, however that is not an immediate option.
On the structure page the entire tree has ridiculous amounts of padding between entries. There are no errors in the console. See screenshot.
********** EDIT *********
Turned on structure debug but there is nothing to debug.
