Fluids don't update when created with commands
Using /setblock or /fill to replace a block with water lava produces a stationary block of that respective fluid. You can do this midair or over another fluid. They will remain unflowing until another block update occurs, relogging does not change this.

I don't understand how this is invalid as a parity issue. I vaguely remember running this command in previous Bedrock versions & now this command has a different result. I'll check some older versions to make sure.
There is still an open report at MCPE-52857 that hasn't been updated in a while.
