Browser Safari 16.4, the bug was not present in 16.3
Related: https://github.com/ajaxorg/ace/issues/5112

This bug breaks copying YAML or Python code from online code editors (Ace, CodeMirror, and Monaco).

When testing, two scenarios:

clipboardData.setData("text/plain", `test1\ntest2\ntest3`)

Results into:

test1
test2
test3

And:

clipboardData.setData("text/plain", `test: 1\ntest2\ntest3`)

Results into:

test: 1test2test3

Eating up all the enters

Could you please try Safari Technology Preview 167? I cannot reproduce with a newer Safari version, so I suspect that this was fixed as part of bug 250119.
