IntelliJ: How can I "kick" the error highlighting process to get it unstuck?

I'm working on a create-react-app codebase with Typescript enabled.
I find that IDEA real-time syntax analysis of my code often gets "stuck".
I make a mistake, IDEA shows the little red squiggles almost immediately, then I fix the errors but sometimes the red squiggles don't always go away.
For example:
There's nothing wrong with the above code any more, but IDEA still shows the red squiggles, both in the code and the project tool window / changelist window.
I've found that I can "un-stick" the code analysis by killing any/all the node.exe sub-process that IDEA has. Presumably one of those sub-process is "stuck" and when I kill the process, IDEA launches a new one and the syntax error highlighting will disappear.
Obviously, I'd prefer that the code analysis not get stuck at all, but failing that is there a way I can "un-stick" the code analysis from within the IDE?
I'm looking for something faster than re-starting IDEA (or clearing caches, etc.)
Using IntelliJ IDEA 2020.3 (Ultimate edition) on Windows.

As per comment from Lena, restarting the Typescript language service will fix issues with stale highlighting errors.
The Typescript status bar widget is usually found at the bottom right of the editor:

After updating Intellij I have this annoying "open browser" pop up whenever I hover over code. How do I get rid of it?

Here is a picture that shows this annoying pop up:
Today I updated Intellij to 2020.1, and that's when I first saw this. It's not fixed mind you. It pops up whenever I hover over my code, which greatly distracts me. Even after disabling all plugins it persists. How can I banish this eyesore to the fiery depths of hell where it belongs?
Open settings. Goto Tools > Web Browsers. Uncheck show popup in editor.
