Export as HTML: Image of text is squished

Question

When exporting a notebook to HTML, the notebook's cells render as images, but the text is often squished. For example, this notebook:

... renders as

If I manually line-break the code, the picture looks ok. However, I'd prefer an automated solution.

Is there a magic incantation to give to Export to have it break the lines before converting them to snapshots?

Thanks.

(There are links related to converting cells to text instead of images: 1, 2, 3. I don't mind the images, if only they didn't squish the text.)

Update 2: The problem was solved by resetting Mathematica to "factory defaults" by holding Alt+Shift while starting the program.

Update: After some experimentation, it seems the line-breaking depends on the size of the notebook's window at the time it was exported to HTML.

To reproduce the problem reliably, try this example, which produces a sequence of longer and longer output lines:

Column[Table[Series[Exp[x], {x, 0, i}], {i, 20}]]

HTML output:

The situation can be helped by outputting to SVG instead of the default GIF, like this:

t = "SVG";
Export["foo.html", EvaluationNotebook[], "Graphics3DOutput" -> t, "GraphicsOutput" -> t, "ManipulateOutput" -> t, "MathOutput" -> t]

This produces a beautiful HTML page like this:

The problem was solved by resetting Mathematica to "factory defaults" by holding Alt+Shift while starting the program (on a Mac). For more details see this link at Wolfram Support.
