Delete button for deleting chats working in landscape mode but not working in portrait mode on Android Tablet Interface.

Hi LMSYS Team,

I am a regular user of the Arena and I’ve identified a bug in the current deployment. I wanted to report this so it can be patched.

Description:
The delete button which is used for deleting chats stops working when used in Portrait mode, but works absolutely fine in the landscape mode.
Although the delete button becomes visible but doesn't respond on clicking it while using in landscape mode.
The bug occurs while using any mode: battle, side by side or direct chat.

Steps to Reproduce:

Go to 'https://lmarena.ai'
Use any mode(battle, side by side or direct chat)
Chat with any model and get the response
Click Menu button
Press Three dots

Expected Behavior:
The delete button shows and on clicking it, the chat gets deleted

Actual Behavior:
The delete button is not visible. It is rather visible backwards when seen carefully, but no response on clicking it.

Environment:
Browser: Google Chrome
Device: Xiaomi Pad 6(Tablet)
OS: Android

Screen Recording:
Screen recording attached for reference.
