How to highlight comment in comment

Hello, I am working on editor, where I use language which support comment in comment, but in editor is highlighting ended with first ‘*/’, is there a way to make all comment higlighted as comment?

1 /* Comment 1
2 some text
3 /* Comment 2 */
4 some text
5 End comment 1 */

In editor are rows 1, 2, 3 higlighted as comment, but rows 4 and 5 as normal code.

It would help so much if you told us which language you are using (and which CodeMirror version).

Sorry, my bad, language is openEdge ABL and version of codemirror 6.65.7.

You’ll have to talk to the maintainers of that language mode—I’ve never heard of it.

Okay, thank you for your time.
