### Summary When pasting multiple filter criteria into the issue search field, some of them are not turned into tokens. ### Steps to reproduce - [open issues](https://gitlab.com/gitlab-org/gitlab-ce/issues) - paste `label:~2fa label:~bug label:~2fa label:~bug label:~2fa label:~bug ` ### What is the current *bug* behavior? Only some labels are turned into tokens:  Also all whitespace between the labels is moved to the end of the input. ### What is the expected *correct* behavior? - all labels are turned into tokens - no trailing whitespace
