Broken coding after cleanup, maybe because of GitHub copilot plugin (?) #465
Description
Hi there, first: Thanks for this amazing plugin, I really love it!
Lately, I got some random behaviours in the output of this plugin. It sometimes created syntax errors or completely mixed up the code on my machine. So I tried to reproduce this behaviour in any meaningful repeabable way, but it occurs quite randomly.
See below the results I got on the dummy class ZCL_ABAP_CLEANER_BUG.abap.txt while triggering cleanup with preview (Ctrl+Shift+4) in different ways and combinations. Unsaved changes and moving the TYPES declaration around seem to help getting these errors.

I think it is some weird interaction between:
- the Github Copilot plugin looking for auto-completions
- unsaved or quite new changes in the coding and
- the delay that comes from opening the ABAP cleaner in preview mode and confirming the proposed changes.
Because while trying to find the reason for this, I got some odd error messages implying that something really strange seems to be going on in the background. Below are some error messages I got. The coding wasn't broken after these. I didn't see any changes happening in the code editor while the ABAP cleaner preview was open.

Save Failed: Anweisung LASS unerwartet Reason: Scanning of the sources failed, see result of syntax check
line 36: Failed referential integrity test on command starting at source line 36: Opening 'CLASS' not closed. Please do not process incomplete code blocks.

From next week on, I'll try deactivating the Copilot plugin and see if this helps. But I wanted to create this issue first, in case someone else has the same behaviour. In case Copilot is innocent, below are the other details of my installation (no updates pending as of today).
