Color formatting goes away for huge XML file

[PascalFilion]

Issue Type: Bug

I have an XML file that is 12.4 MB, 318 328 lines. When I open the file, I see the color for the XML elements but within a second after the file is opened, the colors go away.

Extension version: 2.5.0 VS Code version: Code 1.35.1 (c7d83e57cd18f18026a8162d042843bda1bcf21f, 2019-06-12T14:30:02.622Z) OS version: Windows_NT x64 10.0.18362
