<xliff:g> placeholder tag in Android string xml does not seem to be supported

### Describe the issue

https://developer.android.com/guide/topics/resources/localization#mark-message-parts

> #### Mark message parts that should not be translated
>
> Often strings contain text that should not be translated into other languages. Common examples might be a piece of code, a placeholder for a value, a special symbol, or a name. As you prepare your strings for translation, look for and mark text that should remain as-is, without translation, so that the translator doesn't change it.
>
> To mark text that should not be translated, use an placeholder tag. Here is an example tag that ensures the text "%1$s" isn't changed during translation (otherwise it could break the message):

> ```xml
>
> %1$s until holiday
>

I followed the document to add xliff tags to my strings.xml, however in weblate, it displays the tag directly.

Android string XML:
https://github.com/RikkaApps/WADB/commit/21aa666e25fff327692563766904d1ca69eb22b1

```xml

The translation is contributed by %1$s.

This software is open source (%1$s) under %2$s.
