Specification
https://w3c.github.io/pointerevents/#event-dispatch
Summary
If a pointer is captured while the `pointerup` event is being
dispatched, the `click` event will be dispatched to the
captured target instead of the nearest common ancestor of
`pointerdown` and `pointerup` events as per the UI Event spec.
For uncaptured pointers, the `click` target remains unchanged.

Risks
Interoperability and Compatibility
Interop risk: No risk at all because the major browsers
behaved differently for years (see
https://github.com/w3c/pointerevents/issues/356#issuecomment-811814819).
Compat risk: There is a slight risk that the click target
change would be noticed for a very narrow case of a
slider-like UI element that captures the pointer yet expects a
*container* element to respond to a click differently from how
the slider element itself responds to the same click. For a
drag action that starts on the slider and ends outside the
slider, this feature would cause the click event to be
dispatched to the slider then bubble up to the container (vs
being dispatched to the container element directly).
You mention difference in behavior between browsers - can you clarify
what they all do today?
Also, have we done any compat analysis to have confidence in the "slight
risk" mentioned here?
/Gecko/: Positive
(https://github.com/w3c/pointerevents/issues/356#issuecomment-1596196064)
/WebKit/: No signal
Can we please ask for formal signals from both Mozilla and Apple?
/Web developers/: Positive
(https://github.com/w3c/pointerevents/issues/356#issuecomment-1591894867)
/Other signals/:
WebView application risks
Does this intent deprecate or change behavior of existing
APIs, such that it has potentially high risk for Android
WebView-based applications?
None
Debuggability
None
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?

Anticipated spec changes
Open questions about a feature may be a source of future web
compat or interop issues. Please list open issues (e.g. links
to known github issues in the project for the feature
specification) whose resolution may introduce web
compat/interop risk (e.g., changing to naming or structure of
the API in a non-backward-compatible way).
