[BommerG]

Describe the bug
the help bubble shows strange behavior when the text to display doesn't fit into the available width.
short help: word wrap happens in certain situations before the ellipsis is displayed
full help: there seems to be an invisible tail which gets wrapped in certain situations.

Setup
Please complete the following information along with version numbers, if applicable.

• OS: Linux, openSUSE Leap 15.5, 5.14.21-150500.55.39-default
• Shell: bash
• Terminal Emulator: Gnome Terminal
• Terminal Multiplexer: none
• Locale: en_US.UTF-8, de_CH.UTF-8

To Reproduce
Steps to reproduce the behavior:

1. run the example code
2. change the width of your terminal window to force the help bubble to reduce the output
3. you should see that the left and the right frame don't have the same height in certain situations

Source Code

Expected behavior
the help bubble should always react correctly to the changing width and avoid word wrap or any other behavior that could disturb the correct rendering of the help text.
