W3C Breakout Days 2026 w3c/breakouts-day-2026#3
Patrick: mentioned in a previous call that i had an email from matthew atkinson. specifically this was about longpress. suggested to him to join the breakout day for discussion
Patrick: longpress does feel like ... a strange one. touches on many aspects of when does a UA actually recognise something's a longpress
Patrick: also, most UAs already DO something in response. like iOS/Android bring up a context menu so you can catch it from that
Patrick: will forward his email to the list though
Expose 'inertial scrolling state' in wheel events w3c/pointerevents#587
Vlad: Proposal to expose momentum scrolling in wheel events
flackr: we don'thave wheelstart / wheelend. if we want momentum, feels like we should also have those. but for minimal change, we would want to just expose the delta/that an event was fired as part of the momentum event
smaug: was briefly testing this, and we have something similar internally on gecko. found an oddity on linux where scrolling still happens but no wheel event is fired
flackr: think it's an issue in linux. think it's in the gtk layer. with this proposal, every browser should fire a wheel event with the flag, otherwise some developers now don't get wheel when it's a momentum scroll
smaug: just having a flag should be easy. we'll just have to do something on linux
<plh> https://
Patrick: so sounds like we're in agreement for the principle
flackr: are we ok with the proposed implementation?
could be a boolean, but if we want an unknown value, we can'thave that with boolean
<plh> proposal
as long as we can say in the spec what happens when it's unknown
flackr: i think boolean is ok...
smaug: would be annoying if later on we know that we DO want another value
fuzzy logic, plh
concrete proposal: let's make it a boolean called momentum, to indicate if it's a momentum phase ... thing
smaug: will check with our windows folks first, but should be fine
plh: how are we going to test this?
flackr: we'll have to add the capability to generate these in web driver?
plh: in your proposal you only have desktop. what about mobile?
flackr: but you don't have scrollwheel on touchscreen. but if you attached a mouse you would get it
Patrick: so what's next steps? is there a PR?
Mustaq: I can give it a try
ACTION: Mustaq to create initial PR for #587
<vmpstr> vmpstr
Patrick: any other issues?
<vmpstr> w3c/
vmpstr: raising an issue about overscroll and touch-action interactions, if folks have strong opinions on it, as a heads-up
flackr: was just looking at wheel implementation. there are cases where we have integers rather than boolean. could be 0 or 1 now, but then we can extend...
smaug: i think there was something about using enum values rather than strings...
