Bug 496247

SUMMARY
Application Launcer (start menu button) no longer renders whitespace in the text label. It is no longer possible to increase the button padding size by manually adding spaces as a prefix or suffix for the Text label.


STEPS TO REPRODUCE
1. Right click on a taskbar panel with Application Launcher icon
2. Click on Configure Application Launcher 
3. Under General, type into the Text label spaces, tab characters or no-break-spaces
4. Click on Icon > Remove Icon
5. Click on Apply

OBSERVED RESULT
Application launcher button is extremely narrow with no icon.

EXPECTED RESULT
Application launcher button to be wider than normal with no icon.

ADDITIONAL INFORMATION
Noticed after upgrading from KDE Plasma 5.27.11. I was using a single tab character \t as the Application Launcher text label so the button was wider and removed the icon to reduce clutter on smaller resolution screens.
