After 'Unfasten', unfastened console loses arrow key capability.

Versions

ConEmu build: 170402 x64
OS version: Windows v.1703 build.15063.483 x64
Shell: Bash (WSL)

Problem description

After using 'Unfasten', arrow keys no longer work in the newly unfastened console. I also notice that the little icon indicating which shell is being run (in this case bash/WSL/Ubuntu) is no longer present, so perhaps something is not set right during the unfasten process and arrow keys & maybe other features are accidentally lost? If you start a new shell (tab) within the unfastened window everything works as normal.

Steps to reproduce

1. Start a new bash tab (green + button).
2. Right click on new tab -> 'Close or kill' -> 'Unfasten'

Actual results

Arrow keys no longer work in unfastened console and the tab icon indicating which shell is running is lost (see attached screenshot).

Expected results

Arrow keys work and the tab icon correctly represents which shell is running.
