Flaky specs: Legislation Draft Versions annotations

[javierm]

References

• Pull request Fix flaky annotation specs #4284 was an attempt at fixing this problem

Background

We're selecting a word using a double click. However, the test fails sometimes when styles such as font family, font size or the element's width change, since the double click takes place in the middle of the element and it's possible that the middle of the element contains a space between two words, meaning no word would be selected.

Current behavior

The tests select a random word in the middle of the element; the random word might actually be a space instead of a word

Expected behavior

The tests are consistent and we control which text is selected

Notes

• On some machines, without these changes, the failure in the "Create" test can be reproduced by changing the $base-font-size variable to 2rem or changing the default font family to Roboto
• This failure shows a usability/accessibility issue: adding annotations is hard, particularly when using a touchscreen or a keyboard (see issue Can't add annotations with the keyboard #4831)
