Why does the Insights Debugger display desktop?

On our end, we check:

• if theUser-Agentheader value matches regex that suggests it is a mobile device (i.e. phone, tablet, etc). If it does, we return mobile
• if theX-Algolia-Agentmatches the valueinsights-iosorinsights-android. If it does, we return mobile
• If none of them match but still the event hasUser-Agent, we return desktop
