Two selective !buildbot commands in quick succession causes ALL buildbots to run

[mhsmith]

Running all these unrequested jobs not only clutters the GitHub "checks" list, but also delays other jobs which actually were requested.

Examples:

• 2024-10-28
• 2024-11-18
• 2024-12-03

Until this is fixed, it can be worked around by using a regular expression like android|ios, as in python/cpython#126089 (comment).
