Bug in DS v4.11.0.383 DzSIReloadAction: Sets getScriptFileName() == ""

A Heads-Up in case you are suddenly getting wierd problems in your scripts with v4.11.0.383:

Here's the  test script (also attached as test_01.dsa):

// test_01.dsa
// Script to illustrate a bug in DAZ Studio v4.11.0.383 DzSIReloadAction
//  DzSIReloadAction can be triggered e.g. by menu: Script IDE Pane > File > Reload Script

print( App.longVersionString );

print( ' ' );
var sFileSpec = getScriptFileName();
print( sFileSpec );

print( ' ' );
if( sFileSpec == '' ) {
  print( '### BUG ###: getScriptFileName() == ""' );
} else {
  print( 'OK' );
}
//
// In v4.10.0.123:
//    Works OK, including after executing DzSIReloadAction
//
// In v4.11.0.383:
//    Works OK, until after executing DzSIReloadAction
//      then getScriptFileName() always == ''

print( ' ' );

In the v4.11.0.383 Script IDE Pane:

1. File > Open Script...        // Open test_01.dsa
2. [Execute]                       // It works OK: getScriptFilename() != ""
3. File > Reload Script
4. [Execute]                       // BUG: getScriptFilename() == ""
5. File > Open Script...        // Open test_01.dsa
6. [Execute]                       // BUG: getScriptFilename() == ""
7. File > Close Script
8. File > Open Script...        // Open test_01.dsa
9. [Execute]                       // It works OK: getScriptFilename != ""
10. File > Reload Script
11. [Execute]                       // BUG: getScriptFilename() == ""
