`storagePromptState`; used by `ext-storage.js`
- Fix (regression): Ensure storage dialog will not be blocked because of
canvas updating done for sake of centering background
- Fix (extensions): Ensure `langReady` changes are available by time prefs
dialog is closed and that its changes have occurred by time extensions
have first loaded (`setLang` now returns a Promise rather than `undefined`
as it waits for extension's `langReady` to resolve); this is also useful
with `ext-storage.js` so we know that `extensions_loaded` (which
conditionally updates the canvas based on `storagePromptState`) has seen
`langReady` and the storage extension hasn't set a `storagePromptState`
of "waiting"
- Fix: Allow language to be properly set back to a different locale and
retaining preference (and ensure language changes are available before
dialog closed)
- Refactoring: array extra/spread operator
- npm: Update devDep (sinon-test)
on touch devices (since `touch.js` changes `touchstart` to
`mousedown`) (@ClemArt); closes#168
- Fix: Ensure extension `mouseup` events run on "zoom" and "select"
modes (@iuyiuy); closes#159
to select all (part of #291)
- Enhancement: Add a global escape key listener to clear the selection
- Refactoring: Change 'a' to lower case in key command to avoid impression
that shift is needed
