AW current time "line" breaks visually

1. What happened
When resizing the AW, the current time line (red line) breaks between the top timeline and the canvas/graph area

2. How we can reproduce it using the example you attached
Open the AW with animation on an object
Resize the AW quickly, then stop.
You should see the current time red "line" break vertically (bad)

Workaround:
Sometime updates after a few seconds, sometimes requires a mouse move or click in order for it to refresh properly.
