before this commit: smiley box popover in rtl langauge takes full space it is
because of left:0 given on o_popover class by default, which will be converted
to right:0 when in rtl language and popover position will computed by popper
will set left:'some pixels' due to which it takes full space.
after this commit: smiley box will be displayed with expected width,
unnecessary will not be added, as we have removed left:0 css, hence it will not
be converted to right:0 when in RTL mode.
