extract-i18n generates wrong interpolation equiv-text in v11

🐞 bug report

Is this a regression?

This was working in Angular v10.2.3.

Description

Angular doesn’t seem to generate the correct interpolation equiv-text attributes anymore in Angular v11. When running extract-i18n it previously generated for example:

<source>(<x id="INTERPOLATION" equiv-text="{{ start }}"/>–<x id="INTERPOLATION_1" equiv-text="{{ calculatedEnd }}"/> / <x id="INTERPOLATION_2" equiv-text="{{ totalCount }}"/> results)</source>

now it generates:

<source>(<x id="INTERPOLATION" equiv-text="amMap): void { "/>–<x id="INTERPOLATION_1" equiv-text="usually be a pa"/> / <x id="INTERPOLATION_2" equiv-text="ince it doesn't"/> results)</source>

I have no clue where e.g. the equiv-text ince it doesn't is coming from, that string doesn’t even exist in my app at all.
