MsGraph Todo $filter works incorrectly when have combination of and\or logic conditions

[23W]

Describe the bug
I try to requesting ToDo tasks by MsGraph API from some list and filtering criteria:

• get all tasks that have either Start or Due dates
• and their Title contains some specific text ("dates" in example).

The request is https://graph.microsoft.com/v1.0/me/todo/lists/{myListId}/tasks?$filter=contains(title, 'dates') and (startDateTime/dateTime ne null or dueDateTime/dateTime ne null)

Ms Graph processes this request incorrectly.
It returns result that ignores contains(title, 'dates') criteria and filters by startDateTime/dateTime ne null or dueDateTime/dateTime ne null only.

To Reproduce
Steps to reproduce the behavior:

1. You need to have some ToDo tasks list with tasks that have setup start or due dates. One of the task should have "dates" in its title.
2. Go to Graph Explorer, login with you account that has access to you ToDo tasks list and provide required rights (Tasks.ReadWrite)
3. Execute request https://graph.microsoft.com/v1.0/me/todo/lists/{myListId}/tasks?$filter=contains(title, 'dates') and (startDateTime/dateTime ne null or dueDateTime/dateTime ne null) where {myListId} is Id of your tasks list
4. See error. Result will ignore contains(title, 'dates') criteria and returns tasks filtered by startDateTime/dateTime ne null or dueDateTime/dateTime ne null only.

Expected behavior
MsGraph Todo Service should correctly process $filter criteria and returns the tasks that suits only.

It seems that $filter DOES NOT support OData Grouping (open and close parenthesis “( )”) of logical operations. i.e. filter "(something1) and (something2 or something3)" works INCORRECTLY.
Dear MsGraph team, please update a documentation and make special notes about this limitation.
