The string "a," has currently ..
[RTL] .. reading (or embedding) the string right-to-left:
two items and empty is among its items.
RTL-item 1 is empty, RTL-item 2 is "a".
[LTR] .. reading (or embedding) the string left-to-right:
one item and empty is not among its items.
LTR-item 1 is "a". And LTR-item 2 is empty
(item 2 of "a," is empty --> returns true).
empty is among the items of empty --> returns false
item 1 of empty is empty --> returns true
