Expected behavior

left-clicking with a debug stick should cycle through the available attributes.
For example: on pistons, it defaults to "extended": true/false, but left clicking allows you to instead modify the "facing" value.

Observed/Actual behavior

right-clicking still cycles the selected attribute, but left-clicking does nothing. no toast about the selected attribute, and right clicking still cycles the "extended" state.
If you switch to creative, then change which attribute you're modifying, then it cycles that one, even if you switch back to survival.

This does not seem to be a new issue, as this person posted about it 2 years ago, and their fix was to just use worldedit instead:

(in their attached video, you can see that when they're in survival mode, left-clicking only breaks the glass pane instead of selecting the next direction they can toggle)
Though they were using purpur, but that code still comes all the way back to craftbukkit.

Steps/models to reproduce

• give player the minecraft.debugstick and minecraft.debugstick.always permission
• give the player a debug stick
• set the player into survival
• player left-clicks on any block with multiple attributes that can be modified
• player is still only able to modify the first attribute with right-click
• set player into creative
• left click now correctly chooses the attribute to modify
