This is related to #18413:

Using two symfony application ProjectA and MicroServiceB, if ProjectA issues XHR to MicroServiceB and both have the WebProfilerBundle enabled, then Ajax requests will be monitored in ProjectA. But - at the moment - it will try to look for profiles under ProjectA domain whereas data are stored on MicroServiceB domain.

This PR fixes this issue
