From efbfd14414bd749143fbac386ff163cf5c5be8c8 Mon Sep 17 00:00:00 2001 From: Kevin Brown Date: Sun, 28 Jul 2019 00:36:51 -0400 Subject: [PATCH] Remove selection title attribute if text is empty (#5589) This fixes a bug that was introduced in Select2 4.0.0 and only partially fixed in Select2 4.0.6-rc.0 where the `title` attribute that is set on the selection container (or individual selections, for a multiple select) is not cleared when the text/title of the option is not set. In most cases, users no longer see this issue because the `text` property of most data objects is set, so the `title` attribute will always be cleared correctly. There was a bug for cases where the `text` property was not set, or where the `text` property was set to an empty string, that resulted in the `title` attribute persisting with the incorrect value. We have fixed this issue by always removing the `title` attribute from the selection (or not adding it in the first place, for a multiple select) when the `text` and `title` properties of the data object are empty or not present. This also adds in a series of tests to ensure the `title` attribute is set properly in a variety of cases, building upon the ones that already existed.
