PHP autocomplete doesn't work with latest Intelephense

Describe the bug

Auto-completion is not working anymore/only working partially.

Che version

• latest
• nightly
• other: 7.15.0 (Che-Theia next https://github.com/eclipse/che-theia/commit/2f11124)

Steps to reproduce

1. Set up a Symfony 5 project
2. Use the latest Intelephense version (1.5.3, also reproduced with 1.4.0)
3. Edit some PHP/SCSS files
4. In a controller if I want to write Response as return type, there will be suggestions for R, but if I type Re* or more the suggestions disappear. If I want to write RediretResponse there will be suggestions for R, but not for Re, but again for Red and every following letter. Similar situation for CSS properties in a SCSS file. If I want to write display**, there are no suggestions at all, but after display: i, there will be suggestions for inline-block for example. I tried it in Gitpod and VS Code and there were no issues. See screenshots.

*This error message appears in the console after typing Re (see above):

@ericwill as the devfile and project are work related I can’t share them, but I’ll try to set something simple up to reproduce it.

Thanks for taking a look @ericwill I tested it with Gitpod and it works fine there, they are using Intelephense 1.4.0 so I assume it might be something else. But I would be happy if you could check updating it to 1.5.3. Also, the css issue should be unrelated to the Intelephense version.
