I have a number of reports in polymode where web-mode breaks when used as inner mode (ex polymode/polymode#308, polymode/polymode#270).
I have tracked it down to web-mode scanning on a region wider than the current narrowing. It turned out current scanning machinery does not respect font-lock-dont-widen, hence the fix.
It looks to me that web-mode-scan itself should check for narrowing before running the scans on a wider region but I haven't touched that part because I am not familiar with the code base.
