**What is going on**
Whenever the captcha appears (e.g. after adding around 50 links to the page and hitting the save button in VE) and I try solve the captcha and click save, a new captcha appears. I cannot save the page since the captchas keep refreshing.
I am sure that I did the math correctly :)
**Exptected behaviour**
When I solve the captcha correctlythe page should save.
**Steps to reproduce**
Open up a new page and create a hyperlink to some target. Then copy this hyperlink around 20 times and try to save the page. Now the captcha should appear in order to prevent spammers

**Additional information**
I used Chrome dev tools in order to intercept the messages going to API.php
```
