At https://en.wikipedia.org/w/index.php?title=Wikipedia:VisualEditor/Feedback&oldid=566679647#Spellchecking_wikilinks_causes_odd_behavior en.wp editor Cryptic C62 has identified that spellchecking links causes inconsistent and apparently unpredictable behaviour. Undoing that change sometimes introduces another layer of inconsistent behaviour. On some occasions both correcting the spelling and undoing it works as it should, but there are at least six types of undesired behaviour where some or all of the link is unlinked. Detailed examples are at the above link.
I've found that a similar problem occurs with Chrome on an iPad 3, though with very different results. In this environment, the spellcheck seems to work fine, but undo causes the original string to be appended to the new string, rather than replacing it.
