||||||
|
* document we got some external references and trying
|

|
* to process them right now. Boom.
|

|
*
|
||||||
|
* The obvious solution would be to always call
|
||||||
|
* draw_formatted() with gradual_loading in
|
||||||
|
* doc_loading_callback() and if we are sure the
|
||||||
|
* loading is really over, call it one more time
