How to auto highlight buffer or region in web-mode?

Question

I'm using web-mode 13.1.25, but was until today on 12.x with the same issue.

It seems I need to continually choose Highlight buffer (C-c C-h) as otherwise, certain functions misbehave.

These steps demonstrate the problem:

<body> Foo </body>

<body> Foo</ </body> 3. It completes to the wrong tag.

<body> Foo</body> </body>

If, however, I type Foo, then type C-C C-h to update highlighting, then when typing the closing tag it auto-completes correctly.

Is it possible to have the current region or the entire buffer's syntax highlighting auto-updated when entering text or a tag?

Is there some setting I'm missing? Is there a recommended workflow?

Thanks!

It turned out that having (setq whitespace-line-column 80000) seemed to cause the issue. Commenting that out enabled normal behaviour. See github.com/fxbois/web-mode/issues/730#issuecomment-241332750 — ldeck, Mar 30, 2017 at 18:20

Having (setq whitespace-line-column 80000) in my init.el files turned out to be an incompatible configuration.

Commenting that out enabled webmode to work as expected.

See this github issue for further discussion.
