This is on me. When I got rid of the `_updatePatternLocations` `ThrottledFunc` in the `TermControl`, I didn't add a matching call to `_updatePatternLocations->Run()` in this method.
In #9820, in `TermControl::_ScrollPositionChanged`, there was still a call to `_updatePatternLocations->Run();`. (TermControl.cpp:1655 on the right) https://github.com/microsoft/terminal/pull/9820/files#diff-c10bb023995e88dac6c1d786129284c454c2df739ea547ce462129dc86dc2697R1654#10051 didn't change this
In #10187 I moved the `_updatePatternLocations` throttled func from termcontrol to controlcore. Places it existed before:
* [x] `TermControl::_coreReceivedOutput`: already matched by ControlCore::_connectionOutputHandler
* [x] `TermControl::_ScrollbarChangeHandler` -> added in c20eb9d
* [x] `TermControl::_ScrollPositionChanged` -> `ControlCore::_terminalScrollPositionChanged`

Print a URL, scroll the wheel: it still works.
