Scheduler header stuttering in scrollable mode on resize

[jouwana]

Hey there
I have the scheduler set up and recently added ability to zoom in, using scrollable mode + smaller steps, pretty straightforward, even just keeping same steps but adding scrollable causes these same issues

1. The day name is not sticky and cannot be made sticky via css, as the header element is not part of the scrollable element, however i was able to bypass this issue via javascrips, looking at the left position value of header and setting it on the leftmost day in view (so works in multi day view + scrollable as well). I think this is something that should be built into the system.

2. In scrollable mode, when the scheduler is being resized, for example have a separator that gets bigger and smaller, the header showing the scale stutters, half turns white.. it looks normal if its a one click resize, but not a continuous drag resize. Look at this video:

The only reason the day title remains in place, is that i added a handler for “onScheduleResize” to fix its position.
