Fixed: Bug 48962 - [IN8][Webmail] Bottom line of body format toolbar is no more …
…displayed when the window is resized
Root cause: .height() was used to measure toolbar size during resizing. It always returns the size not including borders.
Solution: Use .outerHeight() to measure toolbar size. .height() still needs to be used when deciding whether the toolbar is empty because .outerHeight() always returns at least the width of the borders.
