I've noticed recently that the calendar date picker is broken when I go to Working On/Edit Timesheet.
When I first go to Edit Timesheet the date for [today] is displayed and a left arrow is visible next to the calendar icon. I can click on the left arrow to get to [yesterday] (which now displays both left and right arrows next to the calendar icon) and I can click on the right arrow to get back to [today]. Working as expected, no problem.
However...
If I click on the calendar icon to get to [yesterday], I get to yesterday and no right arrow is displayed next to the calendar icon (to get back to [today]). Further, if I click on the calendar icon again and click the date for [today], nothing happens and the timesheet stays on [yesterday].
