This is not really a bug. Java has "quasi-connectivity" or BUD(block update detector). The BUD in Java is an old bug but it is used and accepted by the community as a feature. The Bedrock edition pistons seem to work as intended.

Thank you for your report!
However, this issue has been closed as a Duplicate of MCPE-14664

This is working as intended. Java and bedrock have different redstone mechanics.
