Progress Bar Styling Not Rendering due to CORS

[contang0]

I am having the same issue described here. Basically in some environments we cannot access external resources necessary to style some components, such as the Progress bar. Without styling it appears so narrow that I can barely see it, and nothing worked until I manually fed the 4 CSS files as strings to the stylesheets argument.

loading = # contents of "https://cdn.holoviz.org/panel/1.2.0/dist/css/loading.css" as string
progress = # contents of "https://cdn.holoviz.org/panel/1.2.0/dist/css/progress.css" as string
default = # contents of "https://cdn.holoviz.org/panel/1.2.0/dist/bundled/theme/default.css" as string
native = # contents of "https://cdn.holoviz.org/panel/1.2.0/dist/bundled/theme/native.css" as string

progress= pn.indicators.Progress(
          name="Progress",
          width=500,
          active=False,
          stylesheets=[loading, progress, default, native],
      )

ALL software version info

(this library, plus any other relevant software, e.g. bokeh, python, notebook, OS, browser, etc)

panel v1.4.4
python v3.12
chrome
windows 11
