e2e test - zoom plot (#8370)

Verify that plot zoom works.

### QA Notes

@:web @:win @:plots

- [x] default play button based on defined
- [ ] await for plot before timeout? 
- [ ] uncomment R (and put it under the R tests)
- [x] {language} - {description}
- [ ] UI that gives away that the plot has actually loaded (since
relying on element doesn't work)
