Gaps within selected text in labels at certain font sizes
Steps to reproduce
Create a wrapped and selectable GtkLabel (or use this test.ui) and set the font-size via GTK Inspector to 0.95em (or similar values, usually it's more noticeable when the second decimal digit is non-zero).
Current behavior
Gaps within selection at certain font sizes (e.g. 0.95em, like in the screenshot below).
Expected outcome
No gaps in selection at all font sizes.
Version information
