snapshot test fail with escaped characters

[JakobVogelsang]

We use snapshots to test some complex text fields and define patterns for those. To define patterns we use e.g something like this: '\\S*'. This however is causing problems with snapshot tests. When writing new snapshots, it looks like this

<wizard-textfield
      disabled=""
      label="DNSName"
      nullable=""
      pattern="\S*"
>

when we run the tests with existing snapshots however, we get this

<wizard-textfield
       disabled=""
       label="DNSName"
       nullable=""
 -      pattern="\S*"
 +      pattern="S*"
>

I have seen a similar discussion for Jest which has something to do with a pretty-print running that was causing this issue but am not sure, if this is an issue here.
