[Bug] Broker on Mac error to authenticate "Source application does not match redirect uri host. Invalid source app."

The report provides a Blender plugin reproduction and broker logs, but names no MSAL source file or test. Start by reproducing with the linked plugin and compare its Blender run with the standalone src/login.py run, focusing on the redirect URI error. Done means broker authentication succeeds from within Blender; the issue has had no comment for 301 days, so maintainer guidance may be difficult to get.

Describe the bug
A clear and concise description of what the bug is.

We are currently using msal[broker] to develop some Blender plugins that integrate with our Azure SSO.

When creating and running app.acquire_token_interactive() standalone, it works completely fine.
However, when running it from within Blender, the broker seems to do some extra verification of the redirectUri and detects some sort of mismatch.

To Reproduce
Steps to reproduce the behavior:

Clone https://github.com/RecuencoJones/blender-msal-plugin

First, we will verify that login works fine standalone

1. Update .env with corresponding AZURE_AD_TENANT_ID and AZURE_AD_CLIENT_ID, sample values are provided
2. Run just setup to fetch dependencies
3. Run uv run src/login.py
4. Verify success with token output

Now, the same from within Blender plugin

1. Update src/plugin.py with corresponding AZURE_AD_TENANT_ID and AZURE_AD_CLIENT_ID, sample values are provided or export as env variables for blender to pick them up.
2. Run just setup to fetch dependencies
3. Run just install-plugin to build and install the plugin to Blender
4. Open Blender from terminal (/usr/local/bin/blender or /Applications/Blender.app/Contents/MacOS/Blender)
5. Open Sidebar (shortcut n)
6. Open msal panel
7. Click Login
8. Verify success with token output in terminal

What you see instead

Sample debug output and error response from app.acquire_token_interactive():
