[Dialog] Moveable property disallows title text selection

[Lillious]

Describe the bug: When enabling forge-dialog--moveable on a <forge-dialog> window, it prevents the title text from being selectable despite it having the selectable mouse icon.

To Reproduce: Steps to reproduce the behavior:

1. Create a <forge-dialog> element with forge-dialog--moveable
2. Attempt to text highlight the title

Expected behavior: Child elements should not inherit the draggability of the parent element.

Please complete the following information:

• Forge version: v2.13.2
• I have searched existing issues before creating this report? Y
• Browser: All
• Platform: All
• OS: All

Additional context: Possible solutions:

• Allow the use of Alt + mouse down similar to the default browser functionality for selecting link text.
• Disallow child elements from inheriting the draggability of the parent element.
• Provide design guidance so developers can put a visual handle element that indicates the draggability.
