Citation dialog: keep reference panel open without selection
- Reference panel remains opened while the focus is on an input
- The first item from the reference panel is no longer selected by default
to avoid unwanted items being added as a bubble
- The first item from the reference panel is selected only when the
dialog has no bubbles or when a search for a non-empty input has ran
- Shift-Enter from input or reference panel will accept the dialog's
state instead of creating a bubble
- Ensure that the reference panel reloads when a bubble is deleted
- Added button to accept the citation dialog
Some other changes:
- Z-icon and spinner/accept icon occupy the same amount
of space
- Ensure that window's width is 800px
- Set the editor's width dynamically when DOM is loaded
- Remove not used css classes and css adding margins to
z-icon.
- Do not accept/bubbleize while loading
- removed all cursor-related logic. Instead, insert a new input component
each time the user wants to type. The input remain between bubbles
and focusing on one will open the reference panel. Leaving the input hides
the reference panel.
- during drag-drop reordering, lock the editor height so that it doesn't
get out of sync with the window.
- removed the iframe, since it was no longer needed.
- keyboard navigation: Home/End will place an input at the start/end
of the editor and focus it. Tab focuses the last active input if any, or
the input in the end otherwise. Shift-Tab from the editor focuses the
dropdown button if it is active. Tab from the input will focus the first
entry of the reference list. Tab from the reference list will focus the
active input. Shift-ArrowLeft/Right from focused bubble will swap the bubble
with its neighbor. ArrowDown/Up from bubble will open/close the citation dialog.
- when a reference item is selected, previously active input is re-focused.
- aria-properties to have voiceover, JAWS and NVDA read bubbles, inputs and
reference items, as well as announce hints about available keypresses.
- typing from bubble or the reference panel will refocus previously active
input
- different minor updates to make the functionality less janky
- refactoring of refreshing and resizing of the reference panel to
be more straightforward and to only do it when necessary.
E.g. clicking on a bubble and closing the
popover after will not rerun search and just display the old results.
- some throttling logic so that two escape keypresses one after another
when the itemPopover is open do not close the entire dialog
- renamed variables: qfb=dialog, qfe=editor, panel=itemPopover
- use short form of locator string for bubbles
