Editing and saving a custom query in an issues context, that has been created in a gantt view with rendering options, leads to the loss of the saved gantt rendering options.

STR:

create a new custom query in a gantt context with rendering options¶

switch to the issues view¶

click edit to modify the query¶

#* now the gantt rendering options aren't displayed

click save to save the query¶

Expected: the in step one saved gantt rendering options are preserved, despite that the options weren't displayed in the form in step three.
Seen: the saved gantt rendering options are lost during saving in step four.
