Subject: Tooltip/Popover: fix prevented-show lockout and boolean title/content (#42548)
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=180a522930b6e55b45579342e928540d74b3d5b7;p=thirdparty%2Fbootstrap.git

Tooltip/Popover: fix prevented-show lockout and boolean title/content (#42548)

* Tooltip/Popover: reset hover state when show is prevented

A prevented (or not-in-DOM) show() returned early without clearing
_isHovered, leaving it stuck true. For click-triggered tips that made
every later click hit the _enter() early-return, so the tip never
reopened after one preventDefault(). Reset _isHovered on the early
return. Fixes #39861.

* Tooltip/Popover: coerce boolean title/content to strings

data-bs-title="true" / data-bs-content="false" are auto-converted to
booleans by the data-API, which failed the (null|string|element|function)
type check and threw. Extend the existing number-to-string coercion in
_configAfterMerge to booleans. Fixes #41925.

* Bump bundlewatch size thresholds
