- 59afef6 added a duplicate assignment to item.rights that was putting
a TextConstruct(!!!!) in the item JSON field instead of a string
- info.rights was being set to a TextConstruct (preexisting issue!)
The 'blur' event needs to be dispatched by editable-text
before its state is reset (not after) because tagsbox uses
.initialValue in the 'blur' handler.
followup to 101e6d55d5Fixes: #3575
If a parent item and its primary attachment are selected, it should
still say "Show File" rather than "Show Files". This adds the
questionably named `Zotero.Items.numDistinctFileAttachmentsForLabel()`
to try to figure out if we're operating on 0, 1, or >1 items.
Follow-up to #4124
When item is created manually, title field in itemBox
will be focused instead of the title in the itemPane as before.
If the itemBox is collapsed, it will be opened.
Added 'open' setter to item pane section for brevity
Fixes#4111
* tag selector focus edits
- no tabstop on the tag selector scrollable area
- change tag selector's role from default "grid" to "group".
"grid" is not quite correct semantically and leads to
voiceover suggesting irrelevant commands.
- move all keyboard handling logic to tagSelectorList.jsx.
Tabbing through tag selector is now handled in ZoteroPane,
so the only logic left there is arrow navigation
between tags, and there's no reason to not have it
together with the tags list.
- a workaround to deal with focused tags when windowing
kicks in. When a tag is focused, record its index.
Each time tags are re-rendered, if the saved index is not
among rendered tags, refocus it, otherwise, move focus
to the tags list.
- edits to zoteroPaneTest.js focus tests to expect the updated focus
sequence: selected tab -> tabs menu -> sync button -> collectionTree
toolbar -> collectionTree -> tags selector -> itemTree toolbar
- updated tags selector keydown handling to explicitly handle all
tab/shift-tab events using moveFocus. It is more readable and explicit
focus handling for all components is required for programmic tab/shiftTab
events dispatched in tests to actually move focus
Fixes: #3975
