Embedded WebView surfaces (:napplet process, SurfaceControlViewHost) can't
host the soft keyboard or present Chrome's own selection UI, so editing and
selection are relayed to the main process. This lands the working set of that
relay:
- shim.js: fix React-controlled input erase by writing through the native
HTMLInputElement/HTMLTextAreaElement value setter (so React's value tracker
stays in sync); make the host authoritative for selection re-assert (the
editable selectionchange handler only mirrors); report field/caret geometry
and page-text selection geometry; add pageExtend + caret coords (border-width
corrected) for drag-to-extend and the insertion handle.
- RemoteImeView: land caret where tapped on focus (requestFocus before applying
remote state); host-authoritative selection re-assert within a time window;
setText only when text actually changed; wire copy/cut/paste/select-all and
edit callbacks.
- EmbeddedTabLayer: stop resizing the surface on IME show (removes the ~1s
first-letter freeze); draw the selection overlay — toolbar, teardrop
selection handles, and the insertion (cursor) handle.
- EmbeddedImeBridge / Embedded{Napplet,Browser}Controller: carry selection +
caret geometry and the page-selection event across the Messenger channel.
Known limitation (not fixed here): after a field's page is opened in its own
full-screen activity and the user returns, the selection-highlight paint stays
off across all embedded surfaces. DOM selection, the toolbar, and copy still
work — only the native highlight is gone. This is a WebView/Chromium behavior
in off-window surfaces and is not reachable from the app layer.
