Office-js: Outlook web contextual addin can't highlight results that has special chars

[jive-tamaskuzdi]

I'm developing an outlook contextual addin that highlights phone numbers with a regular expression.
Office 365 web Outlook will not highlight any number that has regex special chars, just to give some example: +,(, ).

Expected Behavior

I expect that results that match the provided regex are highlighted and can activate the addin.

Current Behavior

Results seems to be found by Outlook, then during the highlight process it breaks, since it uses the results in a second RegEx, which fails.

Steps to Reproduce, or Live Example

Manifest to match a number starting with +: (it can be reproduced by any other special char)

<ExtensionPoint xsi:type="DetectedEntity">
  <Label resid="contextLabel" />
  <SourceLocation resid="testResId" />
  <Rule xsi:type="RuleCollection" Mode="And">
    <Rule xsi:type="RuleCollection" Mode="Or">
      <Rule xsi:type="ItemIs" ItemType="Message" />
      <Rule xsi:type="ItemIs" ItemType="Appointment" />
    </Rule>
    <Rule xsi:type="ItemHasRegularExpressionMatch" RegExName="Test" RegExValue="\+1" PropertyName="BodyAsPlaintext" Highlight="All"/>
  </Rule>
</ExtensionPoint>

Then open a mail that contains +1 in the message.

Context

I can't highlight phone numbers in outlook for web that has usual special chars +, (,)
When it start with a +, there is also a console error provided below, since it result in an invalid regex for the second round, but for other cases it just simply is not highlighted (for the same reason).

Based on the sourcemap, the issue is probably here, the keyword should be escaped for special chars before provided to regex, or be highlighted in any other way:
