exclude bootstrap is not working correctly

[Jimmi08]

Bug Description

This settings:

    <libraries>
        <library name="bootstrap" version="5" scope="front"/>
    </libraries>
    <stylesheets>
        <css file="default.css" name="Default"   scope='front' exclude="bootstrap"/>
    </stylesheets>  

is loading CDN bootstrap library

<link rel="stylesheet" media="all" property="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" />

How to Reproduce

Core bootstrap5 theme is working because using word bootstrap in stylesheets.

This works too:

    <stylesheets>
        <css file="bootstrap.min.css" name="Legacy"   scope='front' exclude='bootstrap' />
        <css file="default.css" name="Default"   scope='front' exclude="bootstrap"/>
    </stylesheets>   

This is not working:

    <stylesheets>
        <css file="blue.css" name="Default"   scope='front' exclude="bootstrap"/>
        <css file="red.css" name="Default"   scope='front' exclude="bootstrap"/>
    </stylesheets>  

This works:

    <stylesheets>
        <css file="bootstrap.blue.css" name="Default"   scope='front' exclude="bootstrap"/>
        <css file="bootstrap.red.css" name="Default"   scope='front' exclude="bootstrap"/>
    </stylesheets> 

By the way, with one style in xml, style.css is always set as themecss pref, so this doesn't work either:

    <stylesheets>
        <css file="bootstrap.default.css" name="Default"   scope='front' exclude="bootstrap"/>
    </stylesheets>  

Expected Behavior

Not loading bootstrap css from core

PHP

PHP 8.1

Thanks

Workaround:

    <stylesheets>
        <css file="assets/css/bootstrap.min.css" name="Don't use this"  scope='front' exclude="bootstrap"/>
        <css file="default.css" name="Default 2" default='true'  scope='front' exclude="bootstrap"/>
    </stylesheets>

@CaMer0n Is it mandatory to use word "bootstrap" in style name to exclude core bootstrap or this is bug?
This is really important. Thank you.

This is working solution to not load core bootstrap css on frontend, but still have BOOSTRAP defined. No exclude in stylesheet is needed.

    <libraries>
        <library name="bootstrap"
            version="5"
            scope="wysiwyg" 
            files="css" />
        <library name="bootstrap"
            version="5"
            scope="front" 
            files="js" />
        <library name="fontawesome"
            version="5"
            scope="front"
            files="js" />
        <library name="fontawesome"
            version="5"
            scope="wysiwyg"
            files="css" />
    </libraries>

example for stylesheet:

    <stylesheets>
        <css file="main.css"
            name="Main css compiled with bootstrap"
            default='true'
            scope='front'
             />
        <css file="assets/css/lineicons.min.css"
            name="Default"
            scope='wysiwyg' />
    </stylesheets>
