apparently the convention is that hotkeys should follow the letters
according to the layout, and not remain in the qwerty position
this breaks apart the cluster of media controls (uiojkl),
but that's the intended and expected behavior so it should be fine
* only indicate file-history for markdown files since
other files won't load into the editor which makes
that entirely pointless; do file extension instead
* text-editor: in files containing one single line,
^C followed by ^V ^Z would accidentally a letter
and fix unhydrated extensions
only keep characters `>+-*` if there's less than three of them,
and discard entire prefix if there's more
markdown spec only cares about exactly-one or three-or-more, but
let's keep pairs in case anyone use that as unconventional markup
if a reverse-proxy starts hijacking requests and replying with HTML,
don't panic when it fails to decode as a handshake json
fix this for most other json-expecting gizmos too,
and take the opportunity to cleanup some text formatting
window.localStorage was null, so trying to read would fail
seen on falkon 23.08.4 with qtwebengine 5.15.12 (fedora39)
might as well be paranoid about the other failure modes too
(sudden exceptions on reads and/or writes)
* polyfill Set() for gridview (ie9, ie10)
* navpane: do full-page nav if history api is ng (ie9)
* show markdown as plaintext if rendering fails (ie*)
* text-editor: hide preview pane if it doesn't work (ie*)
* explicitly hide toasts on close (ie9, ff10)
* fix crash on keyboard input in modals
* text editor works again (but without markdown preview)
* keyboard hotkeys for the few features that actually work
hitting enter would clear out an entire chain of modals,
because the event didn't get consumed like it should,
so let's make double sure that will be the case
* slightly faster startup / shutdown
* forgot a jinja2 golf
* waste 4KiB changing prismjs back to gz since brotli is https-gated ;_;
* broke support for firefox<52 (non-var functions must be toplevel
or immediately within another function), now even firefox 10 /
centos 6 is somewhat supported again
