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

[23W]

Describe the bug

My app needs 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.

So app does following request:

graphClient.Me.Todo.Lists[myListId].Tasks.GetAsync(rc => rc.QueryParameters.Filter = filter)

where filter is string "contains(title, '[SPECIFIC_TEXT]') and (startDateTime/dateTime ne null or dueDateTime/dateTime ne null)"

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

The more interesting if i do both filtering separately they works good and return correct result:

• filtering by Title only:

filter="contains(title, '[SPECIFIC_TEXT]')";

• filtering by presence of Start\Due dates only:

filter="startDateTime/dateTime ne null or dueDateTime/dateTime ne null";

So it seems filtering works incorrectly when have combination of criteria connected by logical operations "and\or".
I read whole documentation about filtering in MsGraph and sure that my filtering request is built correctly. It seems that MsGraph ToDo service has a bug with filtering.
Could you please advice me how to build filtering request so MsGraph will process it and return correct result?

Expected behavior

MsGrpah should return tasks that are filtered according criteria

How to reproduce

use filter "contains(title, '[SPECIFIC_TEXT]') and (startDateTime/dateTime ne null or dueDateTime/dateTime ne null)"

Seems this is a bug on MsGraph Server side - https://stackoverflow.com/a/79730068/987850

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.
