field_list inside bullet generates wrong tokens

[melassa]

Describe the bug

This markdown text with the field_list plugin enabled:

- test
  :1: 1
  :2: 2

generates this sequence of tokens:

bullet_list_open level: 0
list_item_open level: 1
paragraph_open level: 2
inline level: 3
paragraph_close level: 2
field_list_open level: 2            # error
fieldlist_name_open level: 3
inline level: 4
fieldlist_name_close level: 3
fieldlist_body_open level: 3
paragraph_open level: 4 
inline level: 5
paragraph_close level: 4
field_list_open level: 4             # error
fieldlist_name_open level: 5
inline level: 6
fieldlist_name_close level: 5
fieldlist_body_open level: 5
paragraph_open level: 6
inline level: 7
paragraph_close level: 6
fieldlist_body_close level: 5
field_list_close level: 4
fieldlist_body_close level: 3
field_list_close level: 2
list_item_close level: 1
bullet_list_close level: 0

The plugin creates annidated field_list instead of an unique field_list with two field_name.
Without the bullet, the output is correct (only one field_list):

field_list_open level: 0
fieldlist_name_open level: 1
inline level: 2
fieldlist_name_close level: 1
fieldlist_body_open level: 1
paragraph_open level: 2
inline level: 3
paragraph_close level: 2
fieldlist_body_close level: 1
fieldlist_name_open level: 1
inline level: 2
fieldlist_name_close level: 1
fieldlist_body_open level: 1
paragraph_open level: 2
inline level: 3
paragraph_close level: 2
fieldlist_body_close level: 1
field_list_close level: 0
