Bootstrap (JS) not included in some pages

[magoncalves]

Steps to reproduce the issue

On some pages, the bootstrap.js file (specifically the "<script src="/media/jui/js/bootstrap.min.js?[UUID]" type="text/javascript"></script>" tag) is not included, resulting on no dynamic behavior on bootstrap components (Accordions, in my case).

Expected result

The bootstrap.js being normally included.

Actual result

The dynamic behavior from bootstrap.js components (like accordions) is not present

System information (as much as possible)

Debian 8.10 (Jessie)
Apache 2.4.10
PHP 5.6.33-0+deb8u1
Mysql 5.5.59
Joomla! version 3.8.7

Additional comments

I've needed to downgrade to 3.8.6 because that dynamic behavior is essential in my site, as much information is collapsed on those components.
That is why I don't put any link for you to check.

without knowing what "some pages" are or even what type of page they are it is impossible to help

Joomla core does not arbitrarily load any media, if you require Bootstrap to be loaded you need to ensure it is loaded (a call to JHtml::_('bootstrap.framework'); will take care of this for you) and that you do not rely on other parts of the system to load media for you.

Closing, not a core bug.

[mbabker]

Just to close the loop here, the only change in 3.8.7 where media stopped being loaded was #19787 because the breadcrumb module doesn't use tooltips therefore there is no point in forcing the load of jQuery and Bootstrap. This is a huge if, but if absolutely nothing else on your site's pages was actually causing Bootstrap to get loaded and that was the only spot doing it, that change would have impacted you.

That's it.
#19787 definitely impacted me.

I was using Bootstrap components and they just worked. I've never bothered about including it (it just worked and those components are all around!).
What's the best way that I can load JHtml::_('bootstrap.framework'); so that future updates won't override it? (and in a way that it will be available in all pages)

Add that line to your template.
