fix vector drifts when zoomAnimation is false and zooming via flyTo or pinch
#8794

@plainheart the fix looks great, thank you for looking into this! Since it's not covered by tests currently, I wonder if it would be covered by #8644 — can you take a look? Let's see if it passes if we turn zoomAnimation off there with this fix applied, and fails without. |

I'm not familiar with how to add test cases, so I'd like to ask you to help me to add some appropriate test cases. Thanks! |

@plainheart oh, I mean there's already a test case written in that PR — we just need to check if it still passes with zoomAnimation: false and this fix. |

There was a problem hiding this comment.
@mourner I added the test with zoomAnimation: false.
The current lint error in the main will be fixed with this to.

The reason why this is working is because dragging is prevented: Line 81 in 9793d0a |

Would love to see this in the next release. +1 |
* Update Rotate.js and CompassBearing.js Removed call to non existing function '_unthrottledOnDeviceOrientation' Higher throttling for smoother rotation on device orientation change. Preparation for iOS support. * clean up code + add `deviceorientationabsolute` listener * wrong `off` method * restore: `webkitCompassHeading` = 360 - `alpha` Safari on iOS doesn't implement the spec correctly, because alpha is arbitrary instead of relative to true north. Safari instead offers webkitCompassHeading`, which has the opposite sign to alpha and is also relative to magnetic north instead of true north * automatically disable compass bearing handler on unsupported device * Update index.html This should be 'ondeviceorientation' instead of 'ondeviceorientationabsolute' * Update CompassBearing.js This should be 'ondeviceorientation' instead of 'ondeviceorientationabsolute' * Update Renderer.js Fix for drifting * Apply patch from: Leaflet/Leaflet#8794 * missing semicolon --------- Co-authored-by: Johnny Visser <johnny.visser@spie.com> Co-authored-by: Raruto <Raruto@users.noreply.github.com>

Background
First I'd like to thank @mourner for the fix in #8103, which makes it work when
zoomAnimationistrue.However, as mentioned in #7466, #8644, and my #8103 (comment), it doesn't work when
zoomAnimationis set asfalse.You can refer to the test case
debug/vector/vector-drift.htmladded in this PR to reproduce or the online demo provided by #7466.In this PR, I tried to set the
transform-originas0 0for the container of the SVG/Canvas renderer. By default, it might becenter. I'm not sure if it is right way to fix this bug but it works indeed and looks simple.closes #8117
