Unexpected behavior of docks when multiple editors are opened

When multiple assets are opened in different editors, their docks incorrectly interfere. After opening two assets in a row, the Business Central freezes with an unexpected error. Closing one asset causes unexpected disappearance of the left panel.

See the attached screencast for detailed information. After the assets are opened for the first time, everything seems correct. Once the .dmn file is opened for the second time, the issues start to occur.
