I find one problem that when create terminal widget and start in debug mode, application crash, but if use yarn electron start, it work ok
I create a demo by theia blueprint as follow
1.create a command in theia-blueprint-contribution.tsx and register menu
2.Press F5 to debug electron applications
3.set breakpoint in terminal.start()
4.click Show Terminal menu
5.when application run to breakpoint and you press F10 continue, the application crash, no response.
but if you use yarn electron start to run application and click Show Terminal menu, it works ok
this make it impossible debug terminal widget , is it a bug?
