Hugo 0.139.0 minification breaks Google search results

[chalin]

Minification in Hugo 0.139.0 will convert

<gcse:searchresults-only></gcse:searchresults-only>

into

<gcse :searchresults-only></gcse:searchresults-only>

Notice the space in between the "gcse" and the colon. This prevents search results from being displayed.

Hugo 0.138.0 is fine

Results are showing fine here, the last commit using Hugo 0.138.0:

• https://deploy-preview-5567--opentelemetry.netlify.app/search/?q=load shows search results

  $ curl -s "https://deploy-preview-5567--opentelemetry.netlify.app/search/?q=load" | perl -ne 'print "$&\n" if /<gcse..*?>/g' 
  <gcse:searchresults-only>

Hugo 0.139.0 adds space to GCSE tag name

With open-telemetry/opentelemetry.io#5642, we upgraded to Hugo 0.139.0, and you can see the inserted space character in the tag name:

• https://deploy-preview-5642--opentelemetry.netlify.app/search/?q=load

  $ curl -s "https://deploy-preview-5642--opentelemetry.netlify.app/search/?q=load" | perl -ne 'print "$&\n" if /<gcse..*?>/g' 
  <gcse :searchresults-only>
