Debian will drop wxgtk-webview support in 2019. Ubuntu will drop in 2 weeks?

Not sure why you think 2019 - it's already gone from Debian unstable,
and it'll be gone from Debian testing tomorrow or the day after:

https://qa.debian.org/excuses.php?package=wxwidgets3.0

Bringing it back requires a switch to GTK+3, which will involve a
significant amount of work in testing reverse dependencies and getting
bugs in wx's GTK+3 support fixed (and initial investigations suggest
there may be quite a lot).

There was only one reverse dependency in Debian (boinc) which we've
switched to use wxHtmlWindow for now - if you've an Ubuntu-only reverse
dependency, then that's probably something to investigate. You can
see the changes made to boinc here:

I'm talking about stable Debian and stable Ubuntu - I expect Debian stable with this change be published in 2019 and there is time to rebuild this library or switch to another one by applications authors.

This bug report is about change in Ubuntu artful, expected to be released as stable in next 2 weeks. I don't understand why this change is implemented few days before release without chance to rewrite applications using this library.

Ubuntu should follow this Debian change with similar schedule with ability to deliver compatible library version or to update depended applications.

MMEX application have artful packages already prepared and published but they are broken with unmet dependencies now.

From wxHtmlWindow Class Reference:

MMEX application uses wxWebView for displaying dynamic graphical reports using JS so using wxHtmlWindow will not be right solution IMHO.

Status changed to 'Confirmed' because the bug affects multiple users.

There's been a gtk3 build of wxwidgets3.0 packaged for some time now.
