Need to offer a fallback when using the "Group multi-value filters" for single value filters like "keywords" search field.
Create a view with exposed filters:
1. One for keywords(use full text search for examle)
2. Other filters with multi values (dropdown or facets)
3. Add the summary and enable the "Group multi-value filters" option.
4. Use the form search, the summary will show the grouped values for the other filters, but the keywords will only show the label with no value shown.
In the templates/views-filters-summary.html.twig template, add a fallback when checking for the options.has_group_values.
Check for the item.groups as well. If it doesn't exist, then print the plain value.
