Ladder Bugs with 'Link Drowns In Walkable Water' Rule checked

Here are a couple stepladder bugs that happen if the quest rule 'Link Drowns In Walkable Water' is checked:
1: Link uses it on Direct Warp type combos
2: If the screen has the Whistle->Dry Lake Flag checked, then Link would still use the ladder on the water type combos even after playing the whistle to make the water dry up and lose all of its properties. Both the water combos and direct warp combo are on screen 05 of map 1.
Here's a test quest to prove that these occur:

It should be noted that these bugs do not happen if this particular quest rule is turned off.
