bug(mat-list): Bad symmetry on text when line-break in code

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

v14

Description

The text in both matListItemTitle and matListItemLine creates a whitespace at the start and end of the text when the code is broken over multiple lines. This breaks the symmetry of the list items as seen in this example on the docs page

Reproduction

Stackblitz of the issue already showing in the docs page:
https://stackblitz.com/run?file=src%2Fapp%2Flist-variants-example.ts

Works:
<span>Text</span>

Creates extra spacing:

<span>
  Text
</span>

Expected Behavior

Expect the result not to have white spaces when rendered, or to ignore the white spaces. As it worked in v14.

Actual Behavior

Gets an extra white space when the code has line break inside tag. Breaks symmetry

Environment

• Angular: latest v15
• CDK/Material: latest v15
• Browser(s): All
• Operating System (e.g. Windows, macOS, Ubuntu): All

Commencez par la reproduction StackBlitz, en particulier src/app/list-variants-example.ts, et comparez le balisage rendu de matListItemTitle et matListItemLine avec du contenu span en ligne et multiligne. Suivez l’implémentation pertinente des listes Angular Material à partir de la reproduction et vérifiez que le balisage multiligne est rendu sans espaces blancs en début ou en fin et préserve la symétrie des éléments de liste.
