FileOpen for Read fails on already opened file

[M23]

From v3.3.5.3 Beta release notes:
Fixed: Regression in FileOpen() where it wasn't allowed to open files in read mode if they were already open in write mode.

In v3.3.6.0 you cannot open a file for reading if it is already open:

$h_write = FileOpen('test.txt', 1)

$h_read = FileOpen('test.txt', 0)
If $h_read = -1 Then
    FileClose($h_write)
    MsgBox(0, @AutoItVersion, 'Failed to open handle for read')
EndIf

FileClose($h_write)
FileDelete('test.txt')

The same happens when the file is opened in other apps (although I have now learnt that Notepad does NOT lock its open files).

Also You can't open the same file for reading and for writing. This was possible with the previous versions until 3.3.2.
