operations on remote file (webdav) block sourceview

### What Happened?

We are editing files on a remote server mounted with webdav

Text inputs or even just cursor moving has the sourceview freezing for a couple seconds on a regular basis, i assume as it interacts with the remote server (it does not seem to be saving though). It makes Code fairly unusable alas, because navigating or typing become very choppy.

Save operations (Ctrl+S) has the sourceview freezing

VS Code, as opposed, only freezes up during open operations. It does not seem to freeze during save

### Steps to Reproduce

open remote file with Code. Use a remote maybe somewhat slow?
move around with arrow keys, click around text, type, save

### Expected Behavior

Non-choppy Sourceview, even when saving, such as for VS Code. Maybe by working on a cache, and having an async send an updated version to remote?

### OS Version

8.x (Circe)

### OS Architecture

amd64 (on most hardwares)

### Session Type

Secure Session (Wayland, This is the default)

### Software Version

Latest release (I have run all updates)

### Log Output

```shell

```

El informe identifica los archivos WebDAV remotos y Sourceview como la ruta afectada, pero no menciona ningún archivo fuente ni ninguna prueba. Primero reproduce los bloqueos al navegar, escribir y guardar un archivo remoto; después, rastrea las operaciones relevantes del editor y compara el comportamiento con la interacción fluida esperada descrita en la issue.
