[Android] Popover instantly closes after opening in shadcn version of BlockNote (also occurs in official example)

[piro0919]

Describe the bug
On Android devices, the popover in the shadcn version of BlockNote immediately closes right after opening.
It flashes for a moment and disappears instantly, making it impossible to interact with.
This does not happen on desktop browsers (Chrome/Safari) or iOS.

It seems related to Android’s touch or focus handling — possibly the Popover loses focus right after opening.

To Reproduce

1. Open a BlockNote editor using the shadcn/ui integration.
2. On an Android device (Chrome), tap any button or trigger that opens a Popover (e.g., link insert menu or toolbar).
3. Observe that the Popover opens for less than a frame and instantly disappears.

Misc
It also occurs in the official sample.
