Google tasks API patch overrides time portion

Question

I'm trying to use patch as an update option for a google tasks from the API https://developers.google.com/tasks/reference/rest/v1/tasks/patch. So far as I understand it should update only sent fields, but even if I'm sending only title, it overrides time portion, meaning: I add google task from google tasks app, set date and time; then in my app with https://developers.google.com/tasks/reference/rest/v1/tasks/patch I'm sending title update, task becomes all day and losing time portion

What I'm doing wrong ?

This is an issue that has been reported

The Support documentation says you can report this on Google Issue Tracker. In this case I would find the report created for this and upvote it.

As you mentioned Google Tasks documentation says that the field due should not be affected if your are not explicitly changing that field Due date of the task (as a RFC 3339 timestamp). Optional. The due date only records date information; the time portion of the timestamp is discarded when setting the due date. It isn't possible to read or write the time that a task is due via the API.
