A command started from the command line, an alias, a shortcut or Repeat
now lights the same ribbon button a click on it would, so users learn
where the tools they type live. A button inside a dropdown lights the
dropdown, a slide-out tool lights its group title, a tool hidden in a
collapsed panel lights the panel's opener, and a button on another tab
lights that tab's header. Always on, in the existing active-button blue.
Buttons are matched by the command they dispatch, so ids that differ
from their command still resolve; the tab on show wins when a command
appears twice, and a clicked button keeps its highlight. Transparent
commands leave the running command lit. The #355 rule that a highlight
lasts only while something runs moves from the ribbon click handler into
dispatch_command, so typed commands are cleared the same way.
