The `header=` option will be converted into DNR's `responseHeaders`
condition.
There will be an attempt to convert regex-based values into DNR-
compatible syntax. Not all regex-based patterns can be converted to
use DNR's patterns with `*` and `?` special characters.
The implementation of `header=` option in uBO has been revisited to
improve compatibility with DNR syntax to minimize burden for list
maintainers when creating `header=` filters compatible with both
uBO and uBOL.
The changes:
- Header names are now case-insensitive by default
- Occurrences of `*` in non-regex-based header values now mean
"matches any number of characters"
- Occurrences of `?` in non-regex-based header values now mean
"matches zero or one character"
At time of commit, and as per MDN, only Chromium-based browsers
currently support filtering on repsonse headers:
https://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/API/declarativeNetRequest/HeaderInfo
Also as per MDN, Chromium 121-127 silently ignore the `responseHeaders`
condition, potentially causing undue blocking of network requests.
Currently uBOL support Chromium 122 and later, meaning we need to mind
potential false positives in Chromium 122-127 for filters using
`header=` option.

Stable Safari is known to not block certain network requests due to
the current state of the DNR engine in Safari. The warning is to
ensure volunteers are not burdened by issues originating from the
browser.
Eventually Safari's DNR implementation will catch up with the
specification, at which time the warning will be removed.
This is a first step to integrate CodeMirror6 into the project.
As a side effect, this should take care of:

Though most likely the list of no-filtering websites will probably
move to its own pane as in uBO in some future.
Most of the time the URL doesn't change and just forcing a reload
of the page is sufficient. When a document is strict-blocked, the
URL must be updated however.
