[Bug]: Editor closes/deselects automatically after auto-save (Live Sync triggers full UI refresh)

[MurlerDE]

Describe the bug

After opening a snippet and typing, the editor automatically closes (deselects) a few seconds after the user stops typing. The snippet remains in the sidebar but must be manually re-selected to continue editing. The issue occurs regardless of whether the user is actively typing or not — the editor also closes without any input after a short idle period.

To reproduce

1. Open any snippet
2. Type a few characters
3. Stop typing
4. Wait ~2 seconds
5. Editor closes — snippet is deselected in the UI

The latest version is not the exact version, because it is the latest at the moment.

Hello @MurlerDE. Please describe in detail the sequence of actions that leads to the bug (skip it if it's already there). Add screenshots of errors from the console. If possible add a video. Issues marked with need reproduction will be closed if they have no activity within 3 days.

As long as I am actively typing, there are no problems.

However, as soon as I stop typing, it takes about 2 or 3 seconds (likely when the auto-save triggers) and the snippet closes automatically.

The issue was reproduced on both masscode-bin v5.1.1 (AUR) and the official massCode-5.1.1.AppImage, ruling out a packaging issue. OS: CachyOS (Arch-based), KDE Plasma, Wayland.

One important thing from your screenshots: the app normally should not request the main snippets list as just /snippets/ in this view. It should include the current context, for example /snippets/?isInbox=1, /snippets/?folderId=6, /snippets/?isDeleted=0, etc.

In your screenshot, after the deselection, the request appears to be just /snippets/. That suggests the renderer lost the current selection context (folderId, tagId, and libraryFilter) during the storage sync refresh.

Could you please confirm this by clicking the last snippets/ request after the deselection and copying the full Request URL? Also please send the tree response from the same refresh.

this is a screen video of the issue. I will try out the current release version 5.2 and give feedback again.

I used AppImage 5.2.0. The error persists. I also have the console output; perhaps it will help.

The video doesn't show the open sidebar or which folder or library item you have selected.

I can no longer reproduce the error. The interface responds as expected, and the code snippets work as usual. However, there was also a major Linux update, which might have fixed the problem. (massCode-5.1.1.AppImage)

The folder for storing the code snippets is the default folder created during installation: home/user/massCode.

edit: I also installed masscode-bin, and that works without any problems now too.

I have the same issue using v5.4.0 on Mac OS 26.4.1 from the arm-64 image

I've installed down to v5.0.0 and see the same behavior. (will keep going down when I have time)

Update: The lastest working version for me on Mac is 4.7.1
