onInput callback function is called on every mouse click

[lowerends]

Hi,

I noticed that the onInput callback function is triggered each time you enter the input field with the mouse and each time you leave the input field with the mouse. I would expect however that this callback function is only thrown when typing into the input field.
I have an example here: https://stackblitz.com/edit/typescript-4mtlng?file=index.ts (you can see the callback function being called in the console log).

Is there a specific reason for this and is it something that can be avoided?

Thanks!
