Make is_cancelled a property, to match the surrounding convention.
all_success and has_download_failures in this class are properties, and DownloadControl.is_cancelled is also a property. BaseDownloader.is_cancelled is a plain method. A caller who writes if downloader.is_cancelled: gets a bound method object, which is always truthy, so the check silently passes and the download continues.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Prevent queued decode jobs from running after cancellation.
Line 97 submits the bound callable without a cancellation check. If cancellation occurs while work waits in a shared decode executor, the queued callable still decodes and writes the image. The CancelledError handler also waits for that queued work because asyncio.shield leaves its future active.
Wrap func in a context-bound callable that calls self.raise_if_cancelled() before execution. If the coroutine receives CancelledError, cancel future first; wait for cleanup only when the future has already started. Add a one-worker regression test with a blocked first job and a cancelled queued second job.

Do not register failed after_image callbacks as successful.
When call_all_plugin('after_image', ...) raises, this finally block still appends the image to download_success_dict. catch_exception then records the same image in download_failed_image, so finish_manifest() can return a path for an image that the download flow reported as failed.

Retain the removed task-context accessors.
The prior 2.7.6 release exported get_current_control, get_jm_runtime, and get_current_option through __all__ and documented them. Existing direct imports will fail after this change. Keep deprecated aliases to the corresponding JTC getters until a documented breaking release.
Proposed compatibility aliases
__all__ = (
+ 'get_current_control',
+ 'get_current_option',
+ 'get_jm_runtime',
'get_jm_task_context',
'jm_task_context',
)
get_jm_task_context = JTC.get_context
+get_current_control = JTC.get_control
+get_jm_runtime = JTC.get_runtime
+get_current_option = JTC.get_option📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
