Short description of error
Timeline seek bar not moving on left click.it's moving on right click only.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
When trying to move/position the blue seek bar in the timeline using clicking on a particular frame it doesn't move, but moving on right click. While on Left click select this should not happen right?
