Outline hierarchy wrong for higher levels

[doe300]

When editing following code, the outline view shows the entry H4 - Test 7 in the same level as H3 - Test 4 instead of showing is at a child of H3 - Test 4. Consequentially, collapsing H3 - Test 4 does not hide H4 - Test 7.

= Test1

== Test 2

== Test 3

=== Test 4

==== Test 5

===== Test 6

==== Test 7

This section should be part of the Test 4 section


=== Test 8

Here, the hierarchy is correct again

What is shown:

• H2 - Test 2
• H2 - Test 3
  • H 3 - Test 4
    • H 4 - Test 5
      • H 5 - Test 6
  • H 4 - Test 7
  • H 3 - Test 8

What should be shown:

• H2 - Test 2
• H2 - Test 3
  • H 3 - Test 4
    • H 4 - Test 5
      • H 5 - Test 6
    • H 4 - Test 7
  • H 3 - Test 8
