On my system this looks like (Ligature LAM-ALIF) plus (FATHA), which is
what one might expect. This is running BabelPad 6.0 on Windows 7, with
Uniscribe 1.0626.7601.17561, using Arial as the Arabic font.

See ligature rule L1 on page 250 of TUS 6.0:

L1 Transparent characters do not affect the ligating behavior of base
(nontransparent)
characters. For example:

ALEFr + FATHAn + LAMl → (LAM-ALEF)n + FATHAn

In general, you cannot expect to get an answer to a question like "Why
doesn't this sequence display correctly on my browser?" without
providing at a minimum:

- the operating system, including version
- the browser, including version
- the font
