Inspection warning banners do not disappear in LaTeX files

[dgelessus]

Some inspections, like "Problematic whitespace" (which highlights mixed tabs/spaces indentation), show a warning banner above the editor. When such an inspection is triggered in a LaTeX file, it never goes away, even after the problem is fixed. This causes the warning banners to accumulate over time, which quickly makes the editor unusable:

This problem does not occur with any other file types (such as Java), it's specific to the LaTeX file type provided by this plugin.

As you can see in the screenshot, the problem happens with multiple different inspections. (The first inspection is the "Problematic whitespace" inspection from IntelliJ, the other inspection is "Zero Width Unicode Character" from the plugin "Zero Width Characters locator".)

I've also reported this issue to JetBrains (https://youtrack.jetbrains.com/issue/IDEA-198008), who have asked me to report it here, since it only happens with this plugin.
