Describe the bug

When you load a Select component with options and select one, if you select the same one that's already selected, it will fire an onChange event and I don't think that's normal behavior for a Select since the value is not actually changing. I tried it using both the regular format and the object format, both using a controlled Select component.

To reproduce:

1. In the codesandbox provided, select "Item 1" in one of the Select components at least twice in a row. The onChange event will write a message to the console each time.

The codesandbox is in 7.11.0 version of Mantine, but my personal repo where I was seeing the issue is v7.10.2.

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