Returns [code]true[/code] if the caret is visible on the screen.
Returns [code]true[/code] if the caret is visible, [code]false[/code] otherwise. A caret will be considered hidden if it is outside the scrollable area when scrolling is enabled.
[b]Note:[/b] [method is_caret_visible] does not account for a caret being off-screen if it is still within the scrollable area. It will return [code]true[/code] even if the caret is off-screen as long as it meets [TextEdit]'s own conditions for being visible. This includes uses of [member scroll_fit_content_width] and [member scroll_fit_content_height] that cause the [TextEdit] to expand beyond the viewport's bounds.
