Bangladesh had the chance to dismiss Chandimal on 79 but Liton dropped a catch down the leg side off Hasan.
The off-spinner was at fault a few overs later when he could not get his hand on to an edge by Dickwella off Taijul Islam and the ball raced for four.
Dickwella made Bangladesh pay for the miss as he hit the next two balls for fours, the second one taking Sri Lanka past 600 runs.
