Research direction

Examine the watcher implementation in uiautomator2, likely in the `watcher.py` file, to understand how regex patterns are compiled and applied. The issue suggests that the watcher's `when` method does not match without an explicit `^` anchor, indicating the regex is used with `re.search` (which matches anywhere) but the user expects `re.match` behavior (anchored at start). Verify the current regex method and consider changing to `re.match` or adding automatic anchoring to fix the inconsistency. Check any related documentation or tests for expected behavior.
