It seems that it's a crash in this TIP. https://github.com/wishstudio/weasel/tree/master/WeaselTSF According to these crash reports: * https://crash-stats.mozilla.org/report/index/d220fcd7-f70e-460b-a884-708b20230601 * https://crash-stats.mozilla.org/report/index/4d5da2c3-3b71-47ad-b3e8-32f560230612 The crash occurs during a call of [`ITfKeystrokeMgr::TestKeyDown()`](https://searchfox.org/mozilla-central/rev/f76d80e486028313488d05f4e7fe2509cec11777/widget/windows/TSFTextStore.cpp#7039) or [`ITfKeystrokeMgr::TestKeyUp()`](https://searchfox.org/mozilla-central/rev/f76d80e486028313488d05f4e7fe2509cec11777/widget/windows/TSFTextStore.cpp#7065). While calling them, [we guarantee the lifetime of `ITfKeystrokeMgr` with a local `RefPtr`](https://searchfox.org/mozilla-central/rev/f76d80e486028313488d05f4e7fe2509cec11777/widget/windows/TSFTextStore.cpp#7038,7064) which is the only ref-countable object which we need to guarantee the lifetime. Therefore, I think that we can do nothing from the our side.
