You can reproduce it on the Roq blog dir
start dev, edit the web-bundler js
and then open the index again

It's the problem connected to io.quarkus.qute.runtime.devmode.QuteSetup. In order to support quarkus.qute.dev-mode.no-restart-templates we attempt to reload all templates when a no-restart change is detected. However, message bundles are not reflected in this logic.

I don't think we could reliably identify the set of templates that need to bo reloaded (because of {#include} etc.).

The correct solution is probably to introduce a dedicated TemplateLocator for message bundles... so that the messages can be reloaded automatically.
