TypeError when using vtt with span using version 6.2.5

[morangil]

Description

I set my tracks to nativeAudioTracks: false and nativeTextTracks: false and console is throng an error when there's is a span on my vtt file (such as <i><b>.. )

Error output

VIDEOJS: ERROR: TypeError: Cannot assign to read only property 'localName' of object '#<HTMLElement>'

This happens when vttjs runs in strict mode. We can probably remove localName from vttjs, but I haven't had a change to make this change and test it.
As a workaround for now, try disabling running video.js/vtt.js in strict mode.

Is this resolved by videojs/vtt.js#40?

[gkatsev]

Yes, it does! Looks like it's been in Video.js since 7.7.2: https://github.com/videojs/video.js/blob/main/CHANGELOG.md#772-2019-12-02
Good catch @vermie!
