I'm afraid we need to remove the Webkit-related plugins (Webhelper,
Markdown Preview) from the Windows installer.
This is because Webkit itself is going to be removed from MSYS2:
For the upcoming release we could ship the previous version of Webkit
along with the locally cached old version of ICU (i.e. we will ship ICU
61 *and* 62 in the installer).
But I personally would prefer removing the plugins from the Windows
installer immediately for the reasons mentioned in
and to prevent us from shipping two ICU versions which bloats the
Windows installer even more.
If there are no objections, I will remove all Webkit-related settings
from the Windows installer next week.
