Known issue: no support for streaming requests

[danirod]

It is known that currently some HTTP requests that use HTTP streaming may hang the user interface. An example request of this is https://httpbin.org/range/1500. Other requests may exist.

In general, support for streaming requests and server side events is currently not well tested and this will probably not change until 0.1 gets released in order to focus my limited resources into finishing the first version of the app.
