ScrollContentPresenter horizontal scroll inverts when FlowDirection is RTL in MacOS trackpad

[Mop1398]

Describe the bug

hello.

Screen.Recording.1403-05-22.at.16.39.13.mov

when the ScrollViewer is in RTL , vertical scroll from trackpad is still the same behavior as LTR (trackpad up =>showing new content from down)
but horizontal scroll from trackpad is inverted (trackpad left =>showing new content from left)

it appears only happening with trackpad , (is it about OnScrollGesture from ScrollContentPresenter ?)

basically it seems trackpad going left is binded to show more from later content of scrollview ,which is completely ok when app is LTR , but it is sort of inverted in RTL . (red box in video is the first item to be seen in scrollviewer ,meaning leftmost item in RTL and rightmost item in LTR)

To Reproduce

• make a scrollviewer with flowdirection RTL
• put some contents in it
• do trackpad gestures with macos.

Expected behavior

in Rtl should bring new content from left when trackpad goes right . right to left and left to right scrolls by trackpad should be inverted in RTL .

Avalonia version

OS

macOS

Additional context

couldn't find any attribute of ScrollContentPresenter to invert in horizontal direction.
have tested with windows 10 trackpad , same results.
