Re-allow FloatLabel with Placeholder (silent breaking change)

[muelbr]

Currently it is not possible to set a placeholder on a textfield with float label, because the float label collides with the placeholder when the field ist empty.
Initially it was a Bug and it seems there was some action to fix it but then whole work was cancelled with the explanation that floating labels should not be used with placeholders.

This is not only a breaking change from the previous behaviour, but IMHO also an incorrect interpretation of labels and placeholders. Labels (and therefore floating labels too) are supposed to describe the input content and placeholders are giving a hint or example, mostly about the correct format. There is also a broad agreement about not replacing labels with placeholders because of screenreader behavior.

Also from a library quality standpoint it is not best practice to have properties that collides visually.

Kind regards
