iOS system paste always prepends a space on textboxes

[frenzibyte]

Pasting passwords in osu! on iOS gets annoying because of this. I'm seeing this with the 3-tap paste feature, not sure about pasting using hardware keyboard in iPad.

Potentially related to https://github.com/ppy/osu-framework/issues/5046.

Bumping to p0 as hopefully it should be an easy fix. It's an important one to get right as if it's broken people will be attempting to login and reporting failures due to password pasting wrong (has happened in the past)

Tested this with a hardware keyboard and I cannot reproduce the issue.

(I also cannot test the popover paste item since it does not appear possibly due to the hold to rightclick menu, but the paste button on the software keyboard in iPadOS also works as intended)

Tested on iOS 17.0 (iPad), iOS 16.6 (iPhone) by copying from the Bitwarden app, osu-2023.815.0
