Instant scrolling when changing pages

[RodrigoJuliano]

Is your feature request related to a problem? Please describe.
If you enable smooth scrolling via css styles, forward navigation makes a animated smooth scroll to the top of the page when loading the page.

Describe the solution you'd like
I think this scroll should always be instantaneous.

One way to get this is by passing the 'behavior' parameter to the scroll function.
Change this:

wmr/packages/preact-iso/router.js

Line 122 in 9b425c5

if (wasPush) scrollTo(0, 0);

To:

 if (wasPush) scrollTo({ top: 0, behavior: 'instant' }); 

Additional context
Relates to #496

[RodrigoJuliano]

A complementary suggestion: If the navigation link includes a hash link, then scroll to the element with that id instead of the top

I thought the default behavior of scrollTo(0,0) was instant? Are you seeing this on a specific browser?

[RodrigoJuliano]

I use chrome. The default behavior is 'auto' which should be instantaneous according to the documentation, but in practice it is not. mdn/content#2719

When I test this locally, I am not seeing smooth scrolling - it's instant. Maybe you have a script or extension that is intercepting this and applying smooth scrolling?

[RodrigoJuliano]

I tested it with an empty project and on Edge, and it still happened. Did you add scroll-behavior: smooth; ?

Ah - sorry, I had missed that you were asking for this as a way to override global scrolling-behavior:smooth.
