[已解决] New WPML Translation Editor removes

Background of the issue:
Hello, we try to translate a link with several query parameters with the "new and improved" ATE:
The link in original language:
https://wpml.org/?bla=blubb&blubb=bla
becomes
https://wpml.org/?bla=blubbblubb=bla
in the translation.
The "&" gets deleted in the translation while saving.

Workaround: Reverting to the old ATE in the right top corner of the translation editor "solves" the issue.
