The bug
When covered by flowing water, only full water blocks will kill grass and mycelium. Thus, a source block or full flowing block (first when water flows down one level) are causing block below to revert to dirt. All flowing blocks (7-1) are not affecting the blocks below.

Correct. As far as I know, this was changed in order to fix MC-190124.
But the fix for it decaying too quickly is to make it not decay at all? As the last comment in the referenced ticket states, it means mycelium is impossible to teraform. (Which was tough to begin with as it spreads faster than grass, skips blocks and can spread in the dark, which means careful water management to accomplish) This leaves literally placing solid blocks over the entire surface or digging and replacing as the only alternatives.
Honestly, slow decay seems more realistic when you flood an area, and in the case of a flower farm, the grass will return if given time.
I'd also like to add that this has been an intended feature for the longest time until 1.13 came around. To me this just looks likes a problem you guys weren't able to change to a slower system. A simple flower farm shouldn't throw away an awesome feature.To terraform the mushroom biomes to a vibrant grassy island is really popular and shouldn't be an extremely hard thing to do in survival, please give us other options if you don't like the water mechanic.

Hi there!
I can confirm this. I tested it with randomTickSpeed 10000 and could only see any change in the block under the water source.
