Steps to reproduce the behavior

1. Go to https://primereact.org/inputnumber/#buttons
2. Type something in the input box.
3. Try navigating through the buttons using tab key.
4. The focus goes to next section without going to increment and decrement buttons.

Expected behavior

The focus should go to increment and decrement buttons, and user should be able to press enter and update values.

Start at the InputNumber buttons demo at https://primereact.org/inputnumber/#buttons and reproduce the issue by typing a value, then navigating with Tab. Inspect the InputNumber implementation and verify that increment and decrement buttons receive focus and respond to Enter without skipping to the next section.
