When using the BuyWidget in a React app, the chain/token selector works on desktop and mobile landscape, but in mobile portrait mode (tested on multiple iPhone models in Safari and Chrome), tapping the selector causes the widget to flash briefly and then go completely blank. The main widget loads fine; only the selector triggers this issue. No console errors appear, but I see repeated hasLostFocus V1/V2 events in the logs.

Steps to Reproduce:

Go to https://moneyxpro.com/#/buyfiat on an iPhone (Safari or Chrome) in portrait mode.
Tap the chain/token selector.
Observe: The selector flashes, then the widget goes blank.
Rotating to landscape restores functionality; switching between device sizes in dev tools sometimes temporarily fixes it until refresh.
Tested Devices/Browsers:

iPhone 12, 14, 14 Pro Max (Safari, Chrome)
Chrome/Safari mobile emulation in dev tools
What I’ve Tried:

Wrapping widget in containers with various CSS (minHeight, overflow, etc.)
Ensuring correct viewport meta tag
Testing different widget sizes and themes
No success with any override
Additional Info:

No errors in console, only repeated hasLostFocus V1/V2 events
Issue only occurs in portrait mode

Expected Behavior:
The selector should open and allow chain/token selection in mobile portrait, as it does in landscape and on desktop.
