Subject: [PATCH] org-align-tags: Fix tag alignment in inlinetasks

* lisp/org.el (org-align-tags): Re-use 'line-prefix text property when
`org-indent-mode' is enabled.  The old version partially copy-pasted
the org-indent code and missed the new changes in inlinetask
alignment.  The new approach should be robust against future
org-indent changes.

Fixes 25334.19025.107017.390781@gargle.gargle.HOWL">https://orgmode.org/list/25334.19025.107017.390781@gargle.gargle.HOWL
