Hi,
Thank you for the provided screenshot and steps for reproduction.
Indeed, I was able to observe both of the described behaviors of the DropDownList tools in the Editor after interacting with a ColorPicker tool, i.e., the DropDownList tools flicker instead of being opened as expected, and when the same action is repeated for other DropDownList tools, they remain open.
With the above being said, I logged the unexpected behavior of the Editor as a bug report in our public GitHub repository:
Feel free to subscribe to the above issue in order to stay notified of any updates regarding the resolution process of this Editor bug.
