Cell labels in Gnumeric are oversized #284

Prerequisites

• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.

Checklist to make sure the issue is not on your end

• I have made sure that I do not have multiple versions of the theme installed. Only one version should be installed in either ~/.local/share/themes or /usr/share/themes or ~/.themes
• The file ~/.config/gtk-3.0/gtk.css does not exist. (If it does, backup and remove it.)
• I have logged out and in again.
• Dark theme only. I have enabled adw-gtk3-dark in gnome-tweaks AND set the appearance to dark in gnome-control-center
• The app I'm having an issue with is installed with flatpak. I've installed the theme in ~/.local/share/themes and ran the command sudo flatpak override --filesystem=xdg-data/themes
• The app I'm having an issue with is an actual GTK3 app and is not coded using another toolkit like GTK2, GTK4, QT, etc.
• I have created a new user profile without any modifications except adw-gtk3.

Description

Cell labels in Gnumeric are slightly oversized. They merge into each other and overlap the cell grid. Can this be improved?
