(Creative) Entering Minecart causes player to destroy blocks

I searched for similar issues, didn't find any similarities.

Entering a Minecart in Creative randomly causes the Player Character to destroy blocks within reach, as if the screen was held to mine consecutive blocks. This continues with no touchscreen input.

I expected the Player Character to simply enter the Minecart without further block interaction.

Issue can be resolved by tapping the screen, apparently this "resets" the "Block Interaction" command.
