Some of fonts get lost whenever I play video clip in WebGL

It would be really great if someone can help me out with this problem.I've posted an inquiry on the Unity UI forum, but since there wasn't any reply I am posting the same inquiry here.

---------------------------------------------
Hello, I've encountered a problem while working on a WebGL version game with Unity.

So, this game I am working on a has a video clip that runs in the background when started.
I used the HTML5 video element for WebGL to link WebGL Texture.
(I referred WebGLMovieTexture.jslib, which was included in 'Simple MovieTextures for Unity WebGL' (https://www.assetstore.unity3d.com/en/#!/content/38369 ) and HTML5 audio/video).

The video texture worked fine almost everywhere. However, UnityEngine.UI.Text seemed to not function right when the video was there.


If I don't use the HTML5 video feature fonts appear normally, as they should.


But whenever I use the HTML5 video feature, some of the fonts get lost in the Firefox browser.

I typed in alphabets, and some of letters are lost as you can see in the screenshot attached.

I would like to know why this happens, and how to fix this problem.
Thank you in advance for your help.

 

Thank you for the reply.

I am not really sure what you meant by 'the project'. Do you mean the project which I built with WebGL or the Unity project itself?
Also, how do I post the bug#?

Again, I really appreciate that you left a reply to help me out.
Thank you.
