Comment (by johnjamesjacoby):

 Good catch. If true, it is unintentional, and goes against efforts in the
 past 2 years to allow for and support same-action additions. I am unsure
 if same-priority was ever addressed, and without looking, doubt that there
 are unit-tests for this case.

 Todos:
 * Confirm the bug
 * Find the related resolved issue from recent years
 * Confirm missing test coverage
 * Write tests to reproduce the bug
 * Patch (likely as suggested above) to fix the comparison logic
