fix(replay): Use global visible rect when text layout is not laid out in Compose

[romtsn]

📜 Description

When a Text component does not specify any font parameters (like fontSize, etc.), the underlying TextLayout returns bogus values. So we're checking now if the fontSize != Unspecified (though there may be some other indicators we'd need to use in the future), and if it is we fallback to just masking by global visible bounds.
