Subject: [PATCH 106/124] ui/conversation-web-view.css: Work around oversized
email body height
Sometimes when loading an email body, the viewport for the web view
will be set to 0 (when the web view is hidden or not yet laid out in
the widget hierarchy?). When this happens, since the width of the body
is specified as 100vw, the content width is reduced to the absolute
minimum and hence the content height is stretched right out. Then, when
the web view is displayed, the viewport width increases but the extra
whitespace is never reclaimed (scrollHeight never goes down), so the
height of the web view remains way too large, causing large amounts of
whitespace at the end of the email message (i.e. #283).
To work around this, set a min width for the HTML element so the initial
height of the email body isn't too badly wrong.
