Broken shortcuts for placeholders since some days

### Describe the issue

Since a couple of days (not sure how many, sorry) there is a misalignment on the placeholders style/links in hosted.weblate.org

Now the placeholders in grey appear also on the 'Source change' section, which creates confusion, and if I click on Control it starts enumerating from there.

There is also no color information on the target window when I copy a placeholder, is on white. It used to be that when a placeholder was correct, it will come in blue.

### I already tried

- [x] I've read and searched [the documentation](https://docs.weblate.org/).
- [x] I've searched for similar filed issues in this repository.

### Steps to reproduce the behavior

- Find a string that is marked as needs-editing or Failing check: Placeholders because some change has happened to the source string.
- Click on Ctrl to see the number of the access keys
- Edit the placeholder information. No visual feedback when the placeholder info is wrong (no orange) nor when is right (no blue).
