[BUG] Link Preview doesn't work properly in sendText WEBJS class with some links

[Sysoev86]

The problem is that when a link is contained in WEBJS sendText class, then the preview at the top of the message will not show a summary of the page. But if you send the same link again, then the page preview at the top of the text will be.

Maybe it is necessary to make some delay of sending a message, so that the preview of the page had time to load in chromium?

Interesting, it's likely because of redirect from the original link to https://sauna-sosnovka.ru/?id=7216&tel=9833416932#scroll7 If you open https://sauna-sosnovka.ru/ekj - it return 302 instead of 200 and whatsapp web (chromium) has to follow it.

Even in official WhatsApp Web it takes time to follow all redirects and show the preview.

Works perfectly when I send static links like https://waha.devlike.pro/

Try improving the site itself following https://ogp.me/ with no redirects and we'll try handle it properly in the project side (no ETA tho for that)
