…in#16122)

Parent theme key in theme.json is skipped when theme.json content is analysed, because having a parent theme shouldn't trigger a re-bundle per se.

chore: clarify inactive session closing log messages (vaadin#15905) (v…

…aadin#15943)

When closing inactive VaadinSession the framework prints a log message stating
that it is 'Closing inactive session  <SID>', but this message can be
misunderstood, as it seems that the HTTP session will be closed.
This change updates the log message to make it explicit that the framework is
closing the Vaadin session.

…ntext of a page (vaadin#15824) (vaadin#15861)

When the resource is served without a charset, it seems the encoding of the
page is used to interpret the resource correctly as utf-8. If you load a file
outside the context of a page however, the content is wrong when the charset
is not specified.

Fixes vaadin#15817
