-------------
MDL-60250 - The '/*rtl:ignore*/' directive has been added to the 'left' attribute of the 'popover' class so that
the rtlcss-php tool (https://github.com/moodlehq/rtlcss-php) does not flip this to a 'right' attribute and cause
the popover to be misplaced on the page when the JavaScript calculates the postion of the popover and adds an
overriding inline CSS 'left' attribute which is fine in LTR languages but confuses it in RTL languages.
