example:
"some desc but it looooooooooooooooong, but i need to make this text long for example" -->
"some desc but it looooooooooooooooong,\n but i need to make this text long for example"

This is a vanilla bug. Tooltips should automatically wrap to the length of your screen. On Forge the bug is fixed by Forge so nobody notices it. On Fabric you will need a 3rd party mod to fix the bug. For example Tooltip Fix. Hardcoding this is a bad idea as it will not be consistent across different monitor sizes and GUI scales.
