Code in lists could throw error on parse due to inner <code> tag being
parsed but not actually used within a <pre>, so this updates the
importDOM to disregard childdren for code blocks.
This also improves the invariant implementation to not be so
dev/debugger based, and to include vars in the output.
- Changes to a sort set will now auto-apply to assinged books (basic
chunck through all on save).
- Added book count indicator to sort set list items.
- Deletion now has confirmation and auto-handling of assigned
books/settings.
Only actuall added YT in the end.
Google had changed URL scheme, and Vimeo seems to just be something else
now, can't really browse video pages like before.
Re-used existing route and moved tinymce help to its own different
route. Added test to cover.
Added new external-content block to support in editor UI.
Sibling/child items will now remain at the same visual level during
nesting/un-nested, so only the selected item level is visually altered.
Also added new model-based editor content matching system for tests.
- Makes enter on empty nested list item un-nest instead of just creating
new list items.
- Also updated existing lists tests to use newer helper setup.
Also:
- Added svg loading support (dummy stub) for jest.
- Updated headless test case due to node changes.
- Split out editor change detected to where appropriate.
- Added functions to help with testing, like mocking our context.
To provide more control of the summary as part of details.
To support, added a way to ignore elements during import DOM, allowing
up to read summaries when parsing details without duplicate nodes
involved.
Adds dynamic and fixed (out of DOM order) positioning with location
adjustment depending on space.
Also adds smarter hiding to prevent disappearing when mouse leaves but
within the same space as the toggle.
Hiding since it's not really used, and may mislead on how to set default
app language (which should be done via env options).
Updated test to cover.
For #5356
Changes the name of our spacing variables due to the prefixing -/_
meaning private in the use of new "use" rather than include.
All now modular too, so all variables/mixins are accessed via their
package.
Also renamed variables file to vars for simpler/cleaner access/writing.
eg. '$-m' is now 'vars.$m'
