Reproducible with the Debian testing version of w3m-el-snapshot
(2018-11-12).

The upstream GitHub repo seems fixed on 2019-04-11.

  - https://github.com/emacs-w3m/emacs-w3m/commit/4a78cd5dea4bacd97c03f3550811925cebd5222d

Workaround:
  - (setq w3m-use-filter nil)
  - disable w3m-filter-stackexchange by C-u M-x w3m-toggle-filtering
  - redefine w3m-filter-stackexchange
  - upgrade to the GitHub version (2019-04-11 or later)
  - downgrade to the Debian testing version of w3m-el (2017-01-10)
  - etc.
