multiline paragraph get extra tabulation in formating

[swirly]

What happens ?

Use a file with a paragraph on multiple lines
format it using alt+shift+F

What is expected ?

Consistent formating and same formating on multiple alt+shift+F use

What happens ?

On each alt+shift+F use, subsequent lines in paragraphe get added space

Initial code

{% block cours %}
	<div class="cours">
		<p>
		  multiple line paragraph
                  with another line

*after one format

{% block cours %}
	<div class="cours">
		<p>
                   multiple line paragraph
                              with another line

*after two format

{% block cours %}
	<div class="cours">
		<p>
		  multiple line paragraph
                                        with another line

To be more precise, it happens with other html tags, and it is made with tabs.
If paragraph content is 3 tabs from beginning of line, each subsequent call to format will push second line (and subsequent lines also) 3 tabs away from line beginning. For 4 tabs, this is 4 tabs away, and so on.
