Polygon symbol fill is not working as expected

Dear team,

The below coordinates do not work for fill symbol. The fill color is not coming. Please provide support.

You have to reverse the order of the vertices:

[51.50685501097203,25.308767846478304],
[51.513163566565964, 25.30671163006852],

[51.51376438138189, 25.30069796675457],

[51.50848579403868, 25.29557641823031],

[51.49908733365672, 25.296274823945666],

[51.49526786801695, 25.300775564312445],
[51.497327804536326, 25.306129675695274],

[51.50685501097203,25.308767846478304]

From the documentation:

Clockwise rings are filled and counterclockwise rings are considered holes.
