Terminal (0.7.3451.0) crashes every time I try to cat or curl a html file containing a certain tweet. The entire terminal frame hangs, white out, goes to (Not Responding).
This happens only with the WSL Ubuntu tab and not when I try to cat the same file with powershell in Terminal. It does not crash with WSL under the older 'Ubuntu' launcher from the Windows Store.

Environment

Windows 10 Pro 1909
Win32NT 10.0.18363.0 Microsoft Windows NT 10.0.18363.0

Windows Terminal (Preview) Version: 0.7.3451.0 from the Windows Store
Ubuntu 18.04.3 LTS installed from the Windows Store

Steps to reproduce

WSL Ubuntu from the Windows Store installed, Terminal from Windows Store installed
Launch Windows Terminal
Window chrome down arrow: Ubuntu

curl 'https://twitter.com/EU_Commission/status/1213399676201734146' -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:71.0) Gecko/20100101 Firefox/71.0'

curl starts to display the html from that url, but doesn't complete as the whole window frame hangs at some point during the output

Expected behavior

I expected the whole output from curl to be displayed, and return to the bash prompt

Actual behavior

curl starts displaying html output, but then the whole app frame including all tabs becomes unresponsive.

Although Windows displayed the "sending data to Microsoft" from the crash, I don't have a link to share as this computer has no Microsoft Account associated with it, and the feedback tool appears to require one to view crash data.
