This CL makes "Custom" margins sticky across different preview sessions but also within the same preview session.
Here is a summary of all changes.
- Within same preview session: So far selecting "Custom" was
picking up from whatever the previous selected option was.
Now, "Custom" remembers the specified margins. To test this
select "Custom", do some dragging, then change to another
option and back to "Custom".
- Across preview sessions: Select "Custom", do some dragging,
then print. Open print preview again, the last used custom
margins are remembered.
- There was a bunch of messages sent from JS to get various
info/settings (initiator tab title, measurement system and
number format, last used margin settings, default printer).
I created a single message "getInitialSettings" to get all
at once (they are needed before the 1st preview is is
requested).
