I found a UI bug on the mobile web interface.
The green attachment counter badge (showing the number of images uploaded) overlaps the chat input field.
Because of this, part of the input area is covered and it becomes difficult to tap or type in that region.
This looks like a z-index / stacking issue where the floating badge is rendered above the input bar.
Expected behavior:
The attachment counter badge should stay within the attachment button area and not cover the input field.
I have attached a screenshot showing the issue.
