How to patch js files?

Made a patch for a ticket https://core.trac.ww.wp.xz.cn/ticket/52415. I found a function that rendered a drop-down list to the screen, this function was in \ wp-includes \ js \ dist \ components.js In this file I added my function to correctly display words with apostrophes. But as it turned out, neither SVN nor git can see the changes. GIT does not see it because the \ wp-includes \ js path is written in gitignore, I don’t know why SVN does not see it. I had to make a commit with the -f flag. How to make a patch in such cases? How to make a commit in such cases?
