This has been refactored already. Those were not cleaned up properly.

Useful for longer text in textareas and does not hurt short text 
elements (like text-field).

This way the vertical size can be controlled.

Other elements do implement the interface but do nothing with the 
property. This make all the interface handling a lot easier at the cost 
of having useless variables in some contexts.

By clicking anywhere but elements of the side panels.

The outlines where not completely shown when multiple elements were put 
beside one another. Now the selected elements of pulled to the top and 
the outline is visible.

This is to not make them move (the amount of pixels the border has) when 
selected.

Some things had to be tweaked in regards to positioning and sizing of 
elements.
The drag preview is now done with a separate div, which only shows while 
dragging and has the temporary dimensions of the element. When dropped 
it sets the grid values if the dropzone as before.

* Remove FormService Injection
* Move FormService and form types to player
* Move interface ValueChangeElement to uI-element.ts
* Use interface InputElementValue instead of
string | number | boolean | null

* Add `InputElementValue` as type when needed

Since no default size is set, the default font size is set to 16px, 
which is the browser(?) default on my PC.

Margin between lines and between button and it's label.

Before it was done with a dysfunctional hack. Now with proper extensions 
to existing (tiptap-node-)extensions.
Also reads existing style and sets select-element accordingly.

Use proper types and remove unused vars.

No longer is async. For elements which need upfront source info (media), 
the media prompf is done in the unit service. Here we can keep it 
simple.
Also remove coordinates from factory as this is information that does 
not need to be known here. This is also handled in the unit service 
where applicable.

Remoove unnecessary type casting, unused variables and consoles
statements.

Was using the wrong value for determining what page to delete from. Now 
correctly uses the SelectionService.

Colors and font stuff.

Update npm version info

Now uses tabs and improved order or inputs.
