Describe the bug

Hello,

After upgrading my project to Mantine 7.13.4 (from 7.12.2), I observed that when using ComboBox, the onOpen function is now called each time the <Combobox.Options></Combobox.Options> is modified through onOptionSubmit.

I made a reproduction case here: https://codesandbox.io/p/sandbox/mantine-react-template-forked-763gq7 based on the Mantine Combobox documentation (https://mantine.dev/core/combobox/#usage).
Using Mantine 7.13.4, we can see that the onOpen function is called on each component render which leads to an infinite loop when the Combobox remains opened. If the dependencies are downgraded to 7.13.3, then the "open counter" is only incremented when the Combobox opens, as expected.

Maybe it is related to #7000.

If possible, include a link to a codesandbox with a minimal reproduction

I wonder if it does come from this modification: 716194c#diff-0e3af7a38801d991836a26d7d003ab8b0db7628c36f37b77af245b82ad96974cR159 performed on 7.13.4.

If the onOpen call depends on the onOpen value, then if an onOpen arrow function triggers a re-render of the Combobox (to do a Combobox's store focusSearchInput() for instance) I think that the arrow function evaluates as a new value and triggers a new call to onOpen (in a infinite loop way).
