Describe the bug

There seems to be an issue with the rendering of a Panel in which the content is a multi-line string with ANSI characters for colors. The right hand border is not vertically aligned

text = '\x1b[35mhttps://bpkio-test-adserver.herokuapp.com\x1b[0m\n\x1b[33m /api/v1/vast\x1b[0m\n \x1b[37m\x1b[2m?\x1b[0m \x1b[36mcoll\x1b[0m \x1b[37m\x1b[2m=\x1b[0m \x1b[34m\x1b[1mDAI_Ads\x1b[0m\n \x1b[37m\x1b[2m&\x1b[0m \x1b[36mdur\x1b[0m \x1b[37m\x1b[2m=\x1b[0m \x1b[31m\x1b[22m$_MMVAR_LIVEAR_SLOTDURATION\x1b[0m\n \x1b[37m\x1b[2m&\x1b[0m \x1b[36msessionid\x1b[0m \x1b[37m\x1b[2m=\x1b[0m \x1b[32m\x1b[22m$arg_sessionid\x1b[0m\n \x1b[37m\x1b[2m&\x1b[0m \x1b[36mserviceid\x1b[0m \x1b[37m\x1b[2m=\x1b[0m \x1b[32m\x1b[22m$arg_serviceid\x1b[0m\n \x1b[37m\x1b[2m&\x1b[0m \x1b[36muid$arg_sessionid\x1b[0m \x1b[37m\x1b[2m=\x1b[0m \x1b[34m\x1b[1mNone\x1b[0m'
