I am encountering an issue when theming on Magento CLI 2.3.5-p1.
I want to customize the favicon.

During my first attempt I just drop a new icon on web folder and named it favicon.ico.
It works but only when I am on the customer login page (my theme inherits from blank). So that's the first issue : I want my icon to show on every pages.

Then I tried doing it with an image with custom name. It didn't worked at all. I don't know what to do I have followed EVERY tutorials.

Here is my theme arborescence :

```
|Violette
|-themeviolette
|---Magento_Theme
|-----layout
|-------default_head_blocks.xml
|-----web
|------favicon.ico
|---media
|---registration.php
|---theme.xml

```

My default\_head\_blocks.xml :

```
<?xml version="1.0"?>

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <head>
        <link src="Magento_Theme::vio.ico" rel="icon" sizes="16x16" type="image/x-icon" />
    </head>
</page>

```

Thank you very much for saving me
