Sort JavaScript imports in the CE code
to match our future ESLint configuration.

Remove unnecessary html roles and also remove some
unnecessary tabindexes

Part of our prettier migration; changing the arrow-parens style.

Convert slot names in Vue.js templates
to kebab-case to match our coding style.

This is the final commit that moves Related Issues to FOSS

These are found in 11 files

- Lock vulnerability linked issues
- Move the create issue button to the footer
- Update documentation

Update gray-700 hex value and find and replace all gray-700
with gray-500.

- use gitlab-ui classes where possible
- use GlButton, GlIcon and GlLink where possible
- use correct Pajamas-style spacing
- update aria label to be more descriptive

- fix child overflowing rounded border of parent
- fix vertical alignment of title elements

Make the related issues component used on the Issues page more
extendable so that it can be reused on the standalone vulnerabilities
page

Put widget behind a feature flag

Clicking on the "Add an existing issue" button in an epic
showed the Linked Issues part of the form which was incorrect.
This commit fixes this so it is not shown in this scenario.

Reformat the necessary files as a second step

Changes each instance across 45 files

Removed the :issue_link_types feature flag code in the frontend for
the blocking issues feature

- Changed Related issues to Linked issues
- Issues can have a "blocks", "is blocked by", and "relates to"
  association

only for EE-specific contents under /ee/app/assets/javascripts/[m-z]*

To improve import order rules

Set import/order, import/no-cycle, and import/no-unresolved
as warn to make this update smoother.

Add functionality for boards list
feature flagged to see the wip limits

- On some pages, the weight icon and value are hidden when the issue's weight is 0

Autofixes i18n lints in the ee directory
that were missed in earlier autofixes.

With the new assertions we benefit from:
- Running the test faster
- Testing the real functionality instead of only asserting on
messages

Original design available here:

This commit rearranges the styles in related_items_list
to adhere to stylelint's warnings. It also adds some
utility classes where applicable

To also verify existence of the slots

Also some Prettier changes. Not sure why prettier-all-save
didn’t fix them in the previous commit.

Due date and Weight is EE only features.
We simply cannot move them to ce/vue_shared.
The only way to preserve current functionality while
making the component reusable is using a slot.

We are building related MRs feature and it will have the same
look and feel with related issues widget.
However, related issues is a EE only feature but related MRs is not.
That’s why, to be able to reuse existing components,
I move them to ce/vue_shared and updated references.

This change introduces drag and drop for epics nested inside epics.
Previously it was available only for issues under epics. This commit
adds the same functionality to epics.
