When actively editing a translation, you cannot choose between transcription options to display (if there is more than one transcription)

[kseniaryzhova]

Describe the bug
When the translation editor is open AND the PGPID has more than one transcription, there is no way to choose which transcription to display (if you want to check the wording on something). It just defaults to one transcription and there is no way to switch while in the editor.

To reproduce
Steps to reproduce the behavior:

1. Go to 'PGPID 584'
2. Click on the translation and open the editor.
3. Click on the transcription tile to display the transcrption. (There is more than one for this doc, Gil and Udovitch)
4. See error. Only Gil displays, there is no way to switch while the editor is open.

Expected behavior
When the translation editor is open and there is more than one transcription for the document, I want to be able to switch the display of the transcription as needed. Same thing applies for when the transcription editor is open and there's more than one translation (although that is less likely and less of a use case).
