Bug 修复
- Fix an issue that caused the cursor to be scrolled into view when
focus()was called on IE11. - Fix problem where the cursor cycled through pieces of right-to-left text on Firefox during horizontal motion when the gapcursor plugin was enabled.
- Fix spurious mutation events in Firefox causing mark replacement at end of composition. Restore call to dom.focus on view.focus
- Fix a bug that could cause node views in front of marked nodes to not be destroyed when deleted, and caused confusion in composition handling in some situations.
- Cursor wrappers (a kludge to make sure typed text gets wrapping DOM structure corresponding to the current marks) are now created less eagerly, and in a less invasive way, which resolves a number of problems with composition (especially on Safari) and bidirectional text.
