HTML text direction

Everyone, I hope understands the difference between left to right and right
to left.  They are directional opposites.  Yet, this does not hold true
with the HTML text direction attribute rtl.  Any string or characters
entered into a text box on a webpage, regardless of directional attribute
used, will appear exactly the same, the only difference is the string
alignment within the text box.
>From the www.w3.org website,
https://www.w3.org/International/questions/qa-html-dir, the dir attribute
is used to set the base direction of text for display.  If right to left,
in the literal sense is the exact opposite of left to right, should any
text controlled by the rtl text direction attribute not appear right to
left, i.e. sdrawkcab?  The only visual/display difference is alignment, not
directional as is intended.  I don't know which group within HTML oversees
this, but I would like to propose/suggest a re-definition of the rtl text
direction attribute, and possibly a new feature that actually allows right
to left character input.

Sincerely,
