Only consider buttons with matching types as matching, when comparing
them between redraws to preserve active button state.
We could have avoided a bunch of issues in the past with this. They are
becoming quite common since we use more spacers and invisible elements
to enable certain behavior. Especially with nodes this caused some issues
recently.
Further code in `ui_but_update_old_active_from_new()` assumed matching
button types resulting in undefined behavior.
Fixes heap-buffer-overflow ASAN crash since 8ec9c62d3e.
Steps to reproduce were:
- Open [emitter-closures.blend](/attachments/e7689016-064c-4390-9f02-c2665b2a6a6b)
- Ctrl+Shift+Click on the header of the "Evaluate Closure" node
