Problem

Fixes #1844 - Autocomplete component was not displaying dropdown suggestions when used with Google Places API or similar external services. Users typing partial matches like "mainstreet 7" would not see relevant suggestions like "7 Mainstreet, Hopkins, MN, USA" because there was no exact match between the typed value and source array values.

Root Cause

1. Default matching behavior: suggestionMatch defaulted to 'start', requiring exact matches from the beginning of strings
2. Suggestion visibility logic: showAllSuggestions was set to false when there was a query, hiding potential matches
3. Case sensitivity: Matching was case-sensitive, reducing match probability

Solution

Changes Made

• Enhanced handleQueryChange method: Now shows suggestions while typing when showSuggestionsWhenValueIsSet is explicitly set to true
• Improved matches method: Added case-insensitive search for suggestionMatch="anywhere" and suggestionMatch="word"
• Maintained backward compatibility: All existing functionality preserved - changes only activate when users opt-in with specific props

Code Changes

// Before (line 134):
showAllSuggestions: query ? false : this.props.showSuggestionsWhenValueIsSet

// After:
showAllSuggestions: this.props.showSuggestionsWhenValueIsSet && (!!query || this.props.showSuggestionsWhenValueIsSet)

// Enhanced case-insensitive matching:
return value.toLowerCase().includes(query.toLowerCase());
