What is the current behavior?

Global middleware is not executed in import order, because sort is not stable

Issue Number: N/A

What is the new behavior?

Preserve order of global middleware definitions.
Sort docs state a list of rules that the sort function must adhere to. Current impl violates it and as such the order is not stable. Violation happens when 2 modules are both global but he return value is not 0. so if comparing a,b it retuns a is "bigger" and if comparing b,a it returns b is "bigger".

Does this PR introduce a breaking change?

• Yes
• No
