Bug: Refiling insert extra spaces at beginning of inline-tasks headlines [9.4.6 (9.4.6-12-gdcc3a8-elpaplus @ ~/.config/emacs/elpa/org-plus-contrib-20210823/)]

[Vincent Chouraki <email@vincentchouraki.fr>]

Hello everyone,

When refiling a headline that contains an inlinetask, extra spaces are 
inserted between the beginning of line and the inlinetask headline. The 
number of spaces inserted seems to depend on the difference in depths 
between the current and "refiled" depth of the headline.

For example, starting from :

##### BEGIN EXAMPLE

* Notes
** Notes from meeting 1
* Notes from meeting 2
*************** TODO do this
*************** END

##### END EXAMPLE

Refiling to "* Notes" should results in

##### BEGIN EXAMPLE

* Notes
** Notes from meeting 1
** Notes from meeting 2
*************** TODO do this
*************** END

##### END EXAMPLE

But results instead in

##### BEGIN EXAMPLE

* Notes
** Notes from meeting 1
** Notes from meeting 2
  *************** TODO do this
  *************** END

##### END EXAMPLE

Best regards,

Vincent
