Subject: [PATCH] fix(reader): keep restore-tip notify flag on tab switch
 during startup restore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When reopening with multiple documents, deferred restore guards of
background tabs had their notify flag overwritten by
restoreSavedViewState() calling beginRestoreGuard(false), so the
"restored to last reading position" tip never showed for those tabs.

启动期多文档恢复时，后台页签的恢复守卫被顺延；首次切到该页签时
restoreSavedViewState() 用 beginRestoreGuard(false) 覆盖了待弹条的
通知标志，导致恢复完成后提示条永不出现。

Log: 多文档恢复时保留顺延守卫的弹条通知标志，修复仅首个文档有恢复提示条的问题
PMS: BUG-376441
Influence: 恢复会话中每个有阅读进度的标签页首次切换过去时都会弹出恢复提示条；恢复已完成的页签回切行为不变。
