Image field slug uses backslash on Windows localhost | no thumbnail preview in back office

[Tom-Pich]

Hello to all,

When filling an image field, selecting an image from the library results in slug being displayed with backslash (e.g. images\img02.jpg). This doesn't cause any problem on the front side, but the image thumbnail shows "404 image not found".

Reproduction

On a content type that has an image field :

• choose Upload from library
• select an existing image in the library

Result

The preview thumbnail of the image has the following HTML: <a href="/thumbs/1000×1000/images\img02.jpg" class="editor__image--preview-image" style="background-image: url("/thumbs/400×300/imagesimg02.jpg");"><span class="sr-only">Preview the image</span></a> The url background image is clearly not well-formed (the \ has been ripped instead of being replaced by /). The link href works perfectly.
