[Web UI] Kepler Wallet close X doesn't function

[smides-nest]

The circled X in the upper right corner of the modal dialog that appears when you click the Connect Keplr button on the Web UI at https://webui.dcl.csa-iot.org/ does nothing. The Close button in the lower left does. Suggest removing the circled X.
