What is Prevented Default column in the command log?

[haeguri]

Problem

In my test, type() was called to enter a value in the input element.

cy.getByTestId('input-element').type('cypress.e2e.test');

However, when I checked the results of the Cypress test run,
it was entered only up to "cyp" and "ress.e2e.test" was not entered.

So I checked on Command Log how the type was executed.

Question

(1) What does the Prevented Default column represent in the command log?
Why is Prevented Default marked as true for characters that fail to input? (e.g. "r", "e", "s", "s", ...)

(2) Why don't beforeinput, textInput, input event trigger when entering "ress.e2e.test"?
