Wikimedia Bugzilla is closed!

Only the first two group of numbered list:
#'''Item 1'''
#'''Item 2'''

#;Item 1
#'''Item 2'''

#;Item 1
#;Item 2

are shown correctly:
1. Item 1
2. Item 2

1. Item 1
2. Item 2

1. Item 1
   Item 2

The third one do not convert the # into a numbered item.

The problem exist with any item that use the semi-column to apply the bold title BUT the first one that is shown correctly. For example:
#;Item 1
#;Item 2
#'''Item 3'''
#;Item 4
#'''Item 5'''

show
1. Item 1
   Item 2
2. Item 3
   Item 4
3. Item 5

PS Tested on https://it.wikivoyage.org but I supposed that the bug exist on each wiki
