Multiple bug fixes

【Contents of the fix】
■【IE/Chrome】 Fixed an issue where the image would exceed the column width when a caption was set for the image in certain environments.
(This problem occurs when you use the Classic editor plug-in and select “Center” in “Attachment Display Settings > Alignment” when embedding images (in the media library) and then use a caption.)
■Fixed a bug that the layout was broken (floats were not released) when “Attachments > Alignment” was set to “Left” or “Right” when embedding images (in the media library).
■Updated Page Builder.
・【Firefox、IE】Fixed a bug that Google map would not display properly.
