[SuperTextField][Mobile] - Popover toolbar appears when it shouldn't

[matthew-carroll]

Package Version
main

To Reproduce
Steps to reproduce the behavior:

1. Tap on an empty SuperTextField on mobile

Minimal Reproduction Code
Run the SuperTextField demo

Actual behavior
A popover toolbar appears.

Expected behavior
No popover toolbar should appear because there isn't any content to interact with.

If iOS and Android show a similar behavior to what we have, then feel free to correct me, but this seems wrong.

Platform
Repro'd on iOS, but probably on Android, too.

Flutter version
v.3.22

@matthew-carroll I think the toolbar should be visible so the user can tap the "Paste" button. Should we just hide the "Cut" and "Copy" buttons when there isn't an expanded selection?

@angelosilvestre can you check iOS and Android and check whether a toolbar appears the moment you place the caret or not? I don't think I remember ever seeing a toolbar upon first tap.
