Based on your feedback, I raised the priority of the item.
The popularity of the public item is high, which means that the feature may get included in our short-term planning sooner. Things are dynamic, and I suggest continuing tracking here.
Additionally, I tested our Menu demo on multiple touch devices. As a result, the Menu seems to open/expand correctly on touching. If it's convenient, please test on multiple devices. Then, you can share the results with me and the types of devices.
