Bismuth fails when using binary installation

[Gabe]

This is the same error that was reported to Debian. However, I am encountering this issue when using Ubuntu.

OS Version: Ubuntu 24.04 LTS

Package: kwin-bismuth
Version: 3.1.4-4build2

Following is a direct copy from the other bug report by Petr Gajdůšek, which matches my own experience for what the syslog contains. I have not tried his mentioned solution of recreating the package using dpkg-buildpackage

Justification: renders package unusable

Dear Maintainer,

After upgrade to 3.1.4-4+b1 kwin-bismuth no more works with following error in
syslog:

kwin_x11[3514]: kwin_scripting: Component failed to load:
(file:///usr/share/kwin/scripts/bismuth/contents/ui/main.qml:5:1: Script
file:///usr/share/kwin/scripts/bismuth/contents/code/index.mjs unavailable
kwin_x11[3514]: import "../code/index.mjs" as Bismuth
kwin_x11[3514]: ^,
file:///usr/share/kwin/scripts/bismuth/contents/code/index.mjs:795:10:
Unexpected token `{'
kwin_x11[3514]: static {
kwin_x11[3514]: ^,
file:///usr/share/kwin/scripts/bismuth/contents/code/index.mjs:796:9: Expected
token `('
kwin_x11[3514]: this.id = "MonocleLayout";
kwin_x11[3514]: ^)

The resulting JS oviously uses ES2022 features despite the project's
tsconfig.js has target set to es2016.

After rebuilding the kwin-bismuth package locally on my system (just dpkg-
buildpackage), it works just fine.

Thank you, Petr
