Website links don't work when value starts with `www.`

See this query to find examples: https://overpass-ultra.us/#m=6.51/55.8180/-3.6929&q=PQKgUAKgFglgzgAngghgOwQUwB4oLYAOANpggPIBumATgSnIgI4CuNAngHSTVtIAuCAPbMBAI14FqmBjDQBzBHyikASswyiRfQRhSjBVAIRgQwMAG1R+7AC4A3nauDsAXxcBdANxgAFGADuKGzm-piicDB8mAB+AEQAev5JsV5gAJTewgIAxphoUdSeQA

The website links in the query results don't work. For example, when it is www.123.co.uk and should point to https://www.123.co.uk, it instead points to https://overpass-ultra.us/www.123.co.uk

(The links do work on OSM.org)
