Subject: Tooltip: Avoid creating an unnecessary tooltip when `Tooltip#hide` is called
X-Git-Tag: v3.3.4~68
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=acc5f6575698b8cbaf18892842301c10303c4502;p=thirdparty%2Fbootstrap.git

Tooltip: Avoid creating an unnecessary tooltip when `Tooltip#hide` is called

Fixed performance bug where a tooltip element is created and then immediately destroyed when tooltip.hide() is called and there is no existing tooltip element

Resolves #15557 by merging it.
