Test runner left pane closes after the salesforce application is open #14274

I have tried many solution but after logging in the left pane just disappears, this is still happening on cypress latest version 
this mean cypress is not compatible to test sales force applications .any thought guys?

this sounds like salesforce is busting out of the Cypress iframe. Many websites do not like to be rendered in iframes and Cypress has some workarounds for most framebusting situations. It looks like in the latest version of Cypress there is a flag that may help with testing salesforce, see the issue here: https://github.com/cypress-io/cypress/issues/23640#issuecomment-1376247776

You can see example of setting this config here: https://github.com/cypress-io/cypress/issues/24290#issuecomment-1376214221
