Steps to reproduce the issue

Create a banner. Define the image size.
Create a Banner module, define a class for the module, assign to banner position.

Expected result

The size of the image should be respected for display.
The module class should be used.

Actual result

None of the above...
Even if grid-child container-banner is corrected with dev tools, the svg (in the <div class="header-shape-bottom">) hides part of the banner.

Definitely a release blocker.
