When you select a text input field on the world, a keyboard pops up to allow you to enter text or copy and paste. Here, the copy button itself seems to work correctly, but when I select a text input field, the string that was entered into that field is not entered into the keyboard that pops up. Currently, all text input fields pop up the keyboard, and the pop-up behavior makes it impossible to make the text in the original field selected, making it virtually impossible to copy the string. As it is, the copy button has no reason to exist.

I have confirmed that this issue occurs in multiple worlds (including Udon Tycoon). It is probably practically impossible to copy in all worlds.
