// We use the _line_number Dictionary to store the highest line number where
// a particular key path (e.g. items.size.x) have been displayed in any of the
// views. When a view wants to display a particular key, it pads the text with
// newlines so that the key appears at the maximum line number where it has
// appeared before. If the current line number is higher than the previous
// maximum, the _line_number Dictionary is updated with the new maximum and
// _line_numbers_changed is true.
//
// By looping here and reformatting the text until _line_number is no longer
// changing we ensure that all keys are displayed at the same line in all three
// views, so that we can scroll them simultaneously.
//
// In theory, this could take quite some time for the worst-case scenario and
// it would be better to rewrite the code so that we are formatting the three views
// simultaneously, padding with newlines as we go along. However, that is rather
// hairy to write and this seems to work well for now.
