Vietnamese Telex perhaps referes this result and change its behavior. When typying something, Telex starts composition on Chrome but may not behave so on Gecko. Fortunately, Chromium just returns some attributes when validAttributesForMarkedText: of NSTextInputClient [1] but it doesn't return these styles when attributedSubstringForProposedRange: of NSTextInputClient is called (always returns non-styled plain text) [2]. Therefore, this patch does not touch IMEInputHandler::GetAttributedSubstringFromRange(). *1 <7d85f23cb0/content/browser/renderer_host/render_widget_host_view_mac.mm (2936)> *2 <7d85f23cb0/content/browser/renderer_host/render_widget_host_view_mac.mm (3036)> MozReview-Commit-ID: 1gPIiu4Qbud --HG-- extra : rebase_source : 5336eea303ee157959941dcc4bda2a0931f1f532
