Bugfix
(User-visible)
Component sizes are not theme-dependent, but if the core theme is to be the default, then the tl-demo must look good with it:
Modify the HTML structure so that it no longer looks broken.
The user icon in the navigation is not at the same height as the breadcrumbs. The padding on the left must be removed.\\
Testing
Start the application and open the pages from which the xml file has changed. Check whether there are any other components that look squashed, which can also be fixed quickly. Also test whether the user menu in the navigation is at the same height as the breadcrumb.
