• Browser and Version: Brave based on Chromium: 105.0.5195.102
• Lib: rc-select@^14.1.2

Bug Description
I customized the dropdownRender component. Inside this component is the input box to filter value.
When I remove the text on input by backspace. The selected value is removing the last item. I inspected the library rc-select, I think the root cause from the event listener listen to any input element inside Select component.

Steps to Reproduce

1. Select multiple values.
2. Type some text on input in the dropdown.
3. Type Backspace to remove text on input.

Actual Behavior
The last item on the selected value was removed on Select

Expected Behavior
Shouldn't affect the selected value.

Reproduce the issue from the linked CodeSandbox in App.tsx, using a multiple Select with a custom dropdownRender input. Trace how Backspace events from that nested input reach Select, then verify that deleting its text no longer removes the last selected value.
