[Crash Report] Crash when using eyedropper on Friefox

在 Firefox 中打开一个新的编辑器窗口，选择取色器并点击绘图画布，以复现崩溃。然后检查 node-graph/libraries/wgpu-executor/src/texture_conversion.rs 第 244 行附近的代码，并根据堆栈跟踪追踪纹理下载路径。当取色器不再导致 Firefox 崩溃，并且报告的复现步骤能够成功完成时，即视为完成。

Describe the Crash
Explain clearly what you were doing when the crash occurred.

Steps To Reproduce

1. Open new editor window
2. Click on "eyedropper" icon
3. Click anywhere in the drawing canvas -> crash

Reproducible on https://dev.graphite.art too.

Additional Details
Reproducible in "private window" and in a new Firefox profile with no add-ons.
Couldn't reproduce it in LibreWolf (Firefox derived browser) and Chromium.

Browser and OS
Firefox 153.0.1, Windows 11
