@grgia recently merged #86507, but they are OOO right now, so I'll auto-assign someone else.

Investigation Summary: Classification: Frontend bug. Causing PR: 86507 (fix: default share sheet option to Submit) by @daledah - High confidence. Recommendation: REVERT. PR 86507 introduced a regression where defaultSelectedTab is unconditionally set to SubmitTab on the OnyxTabNavigator even when isFileScannable is false (e.g. sharing a video), causing a crash because SubmitTab is not rendered in that case. Root cause: video MIME types are allowed by SHARE_FILE_MIMETYPE but not by RECEIPT_ALLOWED_FILE_TYPES, so isFileScannable=false and only ShareTab is rendered, but the navigator tries to initialize on SubmitTab which does not exist. Assigned: @daledah @eVoloshchak @grgia. Labels: DeployBlockerCash kept.
