*** Bug 368605 has been marked as a duplicate of this bug. ***
This bug is annoying for RTL users. However, it is a common for all application that use Kirigami Controls.Slider.
This issue appears to have been fixed in the PlasmaComponents3 slider at some point along the way; moving to qqc2-desktop-style where I can still reproduce the issue.
