Find-in-file -> regexp -> using an escaped new line causes freeze until timeout crash prompt.

[veloper]

Type: Bug

1) open a new file 2) paste in the code below. 3) cmd+f 4) select regex toggle button 5) enter in \/\*(.+?)\*\/ -- all should be well 6) now attempt to add an escaped new line into the subselect like so... 7) enter in \/\*(.+?|\n)\*\/ -- right on key-up from the n key it stalls and hangs until the [re-open] or [keep waiting] prompt appears.

Unable to reproduce problem with given regexps (but in VS Code Insiders on Windows 10).

Do you have an additional * or + after )?
