https://github.com/elastic/kibana/issues/191216\r\n\r\nThis PR fixes my
least favourite editor bug - the cursor jumpiness! It\r\nturns out this
was just due to Monaco editor being picky about styles. I\r\nremoved the
margin from the editor since that's what was causing the\r\ncursor to be
off, and then added an equivalent number of pixels
to\r\n`lineDecorationsWidth` so it's visually the same.\r\n\r\nI tracked
the issue back to this PR in 8.15: #186345. It may not make it\r\nin the
last planned 8.15 patch release, but we can backport there
anyway\r\njust in
