A calendar picker is too narrow if user's date setting is for an RTL language.
This affects only desktop Chromium.

For daysAreaEnd, daysAreaElement.offsetWidth is subtracted from startOffset. On the other hand, for yearMonthEnd, yearMonthRightElement.offsetWidth is not subtracted from startOffset. Why?

For yearMonthEnd, we need the distance from the right edge of "main" to the left edge of yearMonthRightElement.
For daysAreaEnd, we need the sum of the followings:
 o the distane from the right edge of "main" to the right edge of the daysAreaElement
 o 7 * maxCellWidth
 o DaysAreaContainerBorder.

We don't use the left edge of the daysAreaElement because we'd like to assign the same width (maxCellWidth) for each of day-of-week columns.
