JIRA Cloud - Bad tokenization while applying JQL suggestion in unfinished statement

Bad tokenization while applying JQL suggestion in unfinished statement

Steps to Reproduce

1. Open JQL search
2. Write incomplete query: "project ="
3. Place cursor after letter 'p'
4. Select any suggestion from the list

Expected Results

suggestion changes the whole word, i.e. "priority ="

Actual Results

suggestion changes only letter 'p': "priorityarent = "

Notes

Also reproducible on following queries:

• "project = "Customer Ops" AND "
• "project = "Customer Ops" AND assignee "

Because of the same reason WORKS, while it shouldn't the following query:

• "project = "Customer Ops" and assAND reporter = currentUser() " -> "project = "Customer Ops" and assigneeAND reporter = currentUser() "

Works OK if query is complete: "project = "Customer Ops"", "project = "Customer Ops" AND assignee = admin"
