In Edge, multiple expression in a html tag is not working

[infuzz]

1. Describe your issue:

In Microsoft Edge (legacy, not the new chromium), riot Tag is not displayed if we have multiple {var} in the same html tag, very strange !
Works : <h1>{ state.message }</h1> <h1>{ state.message2 }</h1>
Does not work : <h1>{ state.message } { state.message2 }</h1>
Does not work too ! : <h1>Hello { state.message }</h1>

Console shows : "Unhandled promise rejection NotAllowedError" but without line number.
