What does this PR do?
This PR adds functionality that automatically reduces the PageHeader subtitle size to
medium
. This is a reasonable value for HPE theme to ensure the subtitle remains smaller than the Heading (see screenshots below).large
was not chosen because it would have the same font-size as the heading.This does not effect Grommet theme which already uses a value of
medium
.This only applies to the default size of PageHeader which is the main use case in HPE applications currently.
