This is just another bad online "piano arrangement."
If it were a real piano arrangement, the "arranger" would have put in pedal markings or some other indicator at the point you highlighted.
There is also no tempo indication. Old Baroque scores often had no tempo markings, but there were tempo conventions for certain meter and typical rhythm patterns. In a modern score leaving off the tempo isn't normal. This isn't just a quibble. When looking at the left hand repeated note figure with doubled thirds played simultaneously in the left hand I wonder just how fast it's expected to be played!
Signs like these tell me there was no thought put into how a performer is actually supposed to play the music. That's a stranger indifference to the performer when the whole point of arranging is to make music available to performers on different instruments. Quite a bit of change can go into an arrangement for the sake of performance on a specific instrument.
Just putting notes in notation software doesn't make an "arrangement." My suspicion is the "arranger" has never even played this from their own "arrangement." They only listed to the notation software playback.
