Failed to decode downloaded font [bower-asset/bootstrap v3.3.5]

[michaelnguyen2021]

since upgrading to bower-asset/bootstrap v3.3.5 (via composer update), I got in Chrome Console

Failed to decode downloaded font: /assets/edae1c82/fonts/glyphicons-halflings-regular.woff2
Failed to decode downloaded font: /assets/edae1c82/fonts/glyphicons-halflings-regular.woff
Failed to decode downloaded font: /assets/edae1c82/fonts/glyphicons-halflings-regular.ttf

Bower-asset/bootstrap v3.3.4 does not have above warnings

Below is the Screenshot showing diff between v3.3.4 and v3.3.5

What's bower-asset/bootstrap? twbs/bootstrap is our Composer package.

Perhaps this is related to our main change in #16359?

[cvrebert]

bower-asset seems to refer to https://github.com/francoispluchino/composer-asset-plugin . So yes, this seems to be a duplicate of #16359.

Presumably the "downloaded fonts" that are failing to decode are actually 404 error pages or something.
The Glyphicons font files themselves weren't changed between v3.3.4 and v3.3.5.
