Dogusata/hot fix file name starts with dot and slash it doesnt have actions

[dogusata]

Problem

• When the given path for a file starts with ./ it doesn't show the file actions and not triggering the file click.
• When there is a long text inside a followup, it should fit until the line ends instead of cropping at fixed 40 chars.

  Solution

• File path actions and onFileClick events are fixed with original file path check instead of the modified one.
• Added followup inner span text overflow structure instead of cropping the text programmatically and added the check for width overflowing to show the tooltip.

This PR also includes:

• File list updates on the example app
• Z-Index fix for letting the Overlay items show properly
