<images> and <alt> changes in English are not sent to Pootle for translation.

Example

The Help page 

https://help.libreoffice.org/6.3/fr/text/smath/01/03090800.html

does not display icons, where the English page

https://help.libreoffice.org/6.3/en-US/text/smath/01/03090800.html

does.

Furthermore, the <alt> values were also changed and are not in Pootle.

For example, a string in source code is 

<paragraph role="paragraph" id="par_idN10081" xml-lang="en-US">

<image id="img_id3145418" src="media/helpimg/starmath/op21401.svg" width="1cm" height="1cm"><alt id="alt_id3145418" xml-lang="en-US">is included in Icon</alt>
</image>

</paragraph>


The same English string in Pootle is 

<image id="img_id3145418" src="media/helpimg/starmath/op21401.png" width="8.47mm" height="8.47mm"><alt id="alt_id3145418">Icon</alt></image>

and the French translation is

<image id="img_id3145418" src="media/helpimg/starmath/op21401.png" width="8.47mm" height="8.47mm"><alt id="alt_id3145418">Icône</alt></image>

Note that the source string has icon now is an SVG file. The image file in Pootle is a PNG file. The <alt> contents has changed, and should have triggered a update in translation. Also, the paragraph is marked for translation by default.
