Wrong cursor shape in RichTextLabel

[timothyqiu]

Godot version: v3.2.beta.custom_build.cd408c525

OS/device including version: macOS Catalina 10.15.2 / MacBook Pro (Retina, 13-inch, Early 2015)

Issue description:

Long lines wrap inside RichTextLabel. When a meta link wraps in the middle, the remaining area of the line turns the mouse cursor into a hand shape:

The signaling is correct: move your mouse into this area triggers the "meta_hover_ended" signal; and clicking the mouse here won't trigger the "meta_clicked" signal (just like an HTML link that wraps in the middle).

Steps to reproduce:

1. Create a RichTextLabel
2. Set its BBCode text to This is a test and [url=test]here isaveryveryvery long link[/url] that wraps
3. Resize the label until it wraps after the text "here"
4. Move your mouse to the right of the text "here"
