Importing siemens-ix.css does not result in the same style as splitting it up in siemens-ix-core.css and chosen themes

What happened?

I wanted to add a custom theme and followed the documentation as stated here
This resulted in a table not being displayed correctly, or the crucial part. Not in the same way which either means there is something wrong with the core-css, or the documentation is kind of misleading in that regard.

I created a simple stack-blitz here: https://stackblitz.com/edit/xnfrdi-ptmfn7?file=src%2Fstyles.css

Toggling between only the siemens-ix.css and the core + theme results in the table formatting differently.

Hello @Endunry.
In the core-css, the dependencies like bootstrap are not included, which is why the tables are not stylled correctly.
