@TrueDoctor's PR #3337 introduced another regression (in addition to the ones reported in #3353 which @0HyperCube fixed in PR #3354) that I just found. It seems that most checkbox labels are now one-time use, meaning they can't be clicked after the first time to cause their checkbox to toggle. I presume this is because the random ID used to associate a label with a checkbox is being randomized and both widgets aren't being updated in unison.

Affected cases:

• File > New and click the "Infinite Canvas" label, which toggles once but can't be toggled again
• File > Export and click the "Transparency" label
• All the individual labels for checkboxes in the Overlays and Snapping menus:
  
• Switch to the Path tool, select a vector object's anchor point, and click the "Colinear Handles" checkbox label in the control bar

Cases which aren't affected:

• File > Preferences and click the "Zoom with Scroll", "Vello Renderer", and "Vector Meshes" checkboxes, these do work multiple times for some reason
