i18n Ivy extactor: missing type="fmt" inside <source>

[mstawick]

🐞 bug report

Is this a regression?

Kind of. Makes translation system (Crowdin in my case) treat the extracted text as a new string

Description

Given following HTML:
<div i18n>You're using a web browser<br/>that we don't support.</div>

Old extractor would produce:
<source>You&apos;re using a web browser<ph id="0" equiv="LINE_BREAK" type="fmt" disp="&lt;br/&gt;"/>that we don&apos;t support.</source>

But with the --ivy flag it produces:
<source>You&apos;re using a web browser<ph id="0" equiv="LINE_BREAK" disp="&lt;br/&gt;"/>that we don&apos;t support.</source>

so the type="fmt" is missing, changing into a new string.

@mstawick thanks for sending this in. I will look into it. It is a bit difficult to accurately identify these "type" attributes for placeholders since the $localize tagged strings do not contain HTML related information.

Can I ask, does the id of the message change? If not, which is what I would expect, why does your tool (Crowdin) treat it as a different message?

[mstawick]

@petebacondarwin It's because Crowdin doesn't understand anything between the tags - it's just a string. So even though the ID is the same, it thinks that the string has changed, marking it as needing translation. So I guess I can have someone just go through all the languages and approve all the "changed" translations. Thanks for looking into this.
