Item backdrop image after update gone

[JayJayZ]

This is a custom theme right? By default, if you click your user picture in Jellyfin, go to Settings > Display and enable Backdrops, it should display. Also clear your cache or Ctrl+F5 to hard reload the page, to be sure.

Yes it's a custom theme. Backdrops are enabled in the settings and clearing the cache was the first thing I did after the update.
file generating the details page for items "itemDetails.[xxx].chunk.js" differs in the section responsible for the tag

Code:

id="itemBackdrop"

old file itemDetails.[xxx].chunk.js:

Code:

...
var i, n = e.querySelector("#itemBackdrop");
                        t.BackdropImageTags && t.BackdropImageTags.length ? (i = r.getScaledImageUrl(t.Id, {
                            type: "Backdrop",
                            maxWidth: I.ZP.getScreenWidth(),
                            index: 0,
                            tag: t.BackdropImageTags[0]
                        }), b.default.lazyImage(n, i)) : t.ParentBackdropItemId && t.ParentBackdropImageTags && t.ParentBackdropImageTags.length ? (i = r.getScaledImageUrl(t.ParentBackdropItemId, {
                            type: "Backdrop",
                            maxWidth: I.ZP.getScreenWidth(),
                            index: 0,
                            tag: t.ParentBackdropImageTags[0]
                        }), b.default.lazyImage(n, i)) : t.ImageTags && t.ImageTags.Primary ? (i = r.getScaledImageUrl(t.Id, {
                            type: "Primary",
                            maxWidth: I.ZP.getScreenWidth(),
                            tag: t.ImageTags.Primary
                        }), b.default.lazyImage(n, i)) : n.style.backgroundImage = ""
...

new file:

Code:

...
                        var i = e.querySelector("#itemBackdrop"),
                            n = (0, U.I)(r, t, {
                                maxWidth: D.Ay.getScreenWidth()
                            }, !1);
                        n ? S.default.lazyImage(i, n) : i.style.backgroundImage = ""

...

maybe it's just a bug in the new version?
