Describe the bug

Description:

Select and MultiSelect components have an issue with the dropdown position after version 8.2.3. If the flip middleware is set to true (its default behavior, or explicitly with comboboxProps={{ middlewares: { flip: true } }}) and the dropdown height is greater than the distance between the Select or MultiSelect input and the bottom of the window, the dropdown changes from top to bottom after the second time it is opened.

Steps to reproduce:

1. Use a Select or MultiSelect component with a @mantine/core version 8.2.3 or later.
   It's also reproducible on the Mantine website on the Select component page and the MultiSelect component page.
2. Place the component near the bottom of the window so there is not enough space for the dropdown.
3. Open the dropdown. As expected, the dropdown appears above the input.
4. Close the dropdown.
5. Open it again. The dropdown appears on top of the selector for a split second, then the position changes to the bottom of the selector.
6. Repeating this toggles the dropdown between top and bottom on each open.

Expected behavior:

The dropdown should stay on top unless there is enough space below the input to display it fully.
