multi-key bindings apply just_pressed retroactively

[PhaestusFox]

at the moment pressing ctrl -> enter is the same as enter -> ctrl this wouldn't be a problem except when you have something happen on ctrl + enter and something different on just enter. what gets triggered and the order is different depending on the order things are pressed;
for example, having something bound to LCtrl + Return and Return will

• on Return+ -> LCtrl+ -> Return- -> LCtrl- = runs Return -> LCtrl + Return
• on LCtrl+ -> Return+ -> Return- -> LCtrl- = runs LCtrl + Return
• on LCtrl+ -> Return+ -> LCtrl- -> Return- = runs LCtrl + Return -> Return
• on Return+ -> LCtrl+ -> LCtrl- -> Return- = runs Return -> LCtrl + Return -> Return

this is not what it should do.

I don't know the best way to fix this but one way would be to have a "final" key that actual check all the other keys are pressed on the frame it gets set to just_pressed so the order of all the other keys don't matter just the last one
and if you wanted something like LCtrl + A + B to trigger regardless of if you pressed A or B last you would just need to bind it twice this only adds N key bindings to any combination of N keys because you only need one binding for each final key not every permutation of said keys
