Script file is not changed if user does not click outside of the field

Summary

When changing script files, if the user saves the changes without clicking away from the file field, the new file is not saved, even if the checker completes.

Steps to reproduce

1. Add a new script (for the purpose of testing, the built-in scripted post-function 'Clones an issue, and links' was used)
2. Use a script file (for example, file A)
3. Save the configuration
4. Edit the configuration, and switch to file B
5. Without clicking away from the field where you specify the file, click on 'Save' directly

Two screen recordings have been attached to better demonstrate this :

• When using files specified in the Script Editor - Script file2.mp4
• When using full paths to specify the script file - Script file.mp4

Expected behaviour

The script file will be changed successfully

Actual results

The script file is not saved

Notes

• On the other hand, if the user clicks away from the field and then saves the changes, even if the checker is not yet complete, the changes will be saved successfully
