Safari UI bug - week schedule swimlane intermittently won't scroll all the way up
Sometimes, when the page loads / reloads after an operation, the week schedule swimlane won't scroll all the way back up. Instead, it gets stuck before the numEvents and time block widgets become visible.
Fixable by collapsing / expanding the swimlane.
Safari Version 11.0.1 (13604.3.5)
I can reproduce this by refreshing the page and scrolling down before all HITs have been loaded. I'm not sure if this is the only way to repro, but it is reliable.
