1987060 - [TSF] Stop extending selection range to cluster boundaries at starting composition and setting selection by IME in release

Status: RESOLVED FIXED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)(sick)]

This is about intl.tsf.hack.extend_setting_selection_range_to_cluster_boundaries pref. We fixed bug 1670834 which introduced the pref 5 years ago. So, I think it's safe to use the stricter behavior in all channels.

Attachment: Bug 1987060 - Stop expanding selection range to cluster boundaries either when IME starts composition or when IME sets selection r=m_kato!,#dom-core

We've extended Selection range which is maybe explicitly set by
IME to cluster boundaries if its range boundary is middle of a cluster.
However, TSF does not define such behavior and IME may want to replace
part of a cluster. Therefore, we should stop do that.

This change was introduced in bug 1670834 about 5 years ago. So, this
must be tested enough in early beta and earlier build testers.
