The "Respawn" and "Title Screen" buttons are locked for the first second after death

When a player dies, they appear on the death screen. And here you can notice that after you die, the “Respawn” and “Title Screen” buttons are initially locked and cannot be clicked on, but after a second they change their texture to normal and these buttons become available for clicking on them. Steps to reproduce:

Write the /kill command in the chat in order to die.

Please note that the two buttons for respawning and exiting the main menu are locked for one second after death. Now switch to full-screen mode with the F11 key (by default) and these buttons will lock again for one second. You can also change the size of the game window vertically and diagonally and the same thing will happen.
