not sure if it’s still relevant, but the issue with the cursor alignment had to do with this bit:
/* highlight (==) not visible anymore if not active line */
div:not(.CodeMirror-activeline) > .CodeMirror-line .cm-formatting-highlight.cm-highlight {
font-size: 0;
}
commenting it out fixed the issue for me… my sacred cursor / text selection now align properly
