Not sure I understand.
What are you trying to solve?
I can't reproduce #23807 here (Firefox) whether I use flex-start or flex-end. The client is always floating as should (depending if lang is ltr or rtl).
Tested by changing the html tag attribute dir from ltr to rtl. While not really a pleasure to look at but the same behavior is exhibited by both Chrome and IE11 so I think it works.
To test rtl, please install the Persian language and use it in back-end.
One gets this (as the pack is 3.x, are missing some lang strings and en-GB string are used)
