1.132.0: Mouse selection triggers unwanted fold collapse in unsaved text files

Does this issue occur when all extensions are disabled?: Yes/No

- VS Code Version:
- OS Version:

Steps to Reproduce:
1. no any add-on
2. no configration file
3. create a new file. do not save it.
4. this is new file content:
a. aaaa
1. 1111
2. 2222

b. bbbb
1. 1111
2. 2222

When I select any character, it will triggers all collapse. not only to new files, but to all file formats: Python, JavaScript, TXT, etc.
only triggers when the mouse double-clicks the content or selects text; it doesn't trigger when the keyboard is pressed.
