Shako how important is this bug to resolve for Gdocs and Quantum Flow

We need platform engineers to review the profile to have more details in this bug.

Hi Naveed, This bug is created based on the profiler data analysis of empty gdoc content test, but since engineers will open the corresponding bugs for different observations from profiler data, I will suggest maybe we can set this bug as duplicate?
