(Lemmy regression!) cannot post new threads using Ungoogled Chromium (Lemmy ver ≥0.19.4)

Lemmy 0.19.4 introduced a quite serious defect whereby if you are using Ungoogled Chromium (and perhaps stock Chromium), the form to create a new post accepts input but then the instant you tab out of the field, the whole field is cleared. Poof… just like that, all your work vanishes and no way to get it back.

Firefox-based browsers have no issue.

Lemmy 0.19.5 seems to have fixed it. But there are other problems with both 0.19.4 and 0.19.5, so I suggest not upgrading past 0.19.3.

(edit) actually the problem manifests differently in 0.19.5. The form can be filled out and there is no data loss, but the “create” button is insensitive. It remains gray and behaves as if the form is still empty.
