This happens for all global types e.g. HTMLxxx, for example:

let x: HTMLImageElement;

x. context assist will show correct img properties list, however, tooltip on HTMLImageElement hover shows

interface HTMLImageElement
var HTMLImageElement: {
 new (): HTMLImageElement;
 prototype: HTMLImageElement;
}

and CTRL+Hover or CTRL+Click results in “java.lang.IllegalArgumentException” popup, the error in the log:

Not sure if it can easily be corrected for browse functionality, but the sudden error popup when hovering with CTRL over source is really disruptive.

Fedor,

Sorry that you are seeing this issue. I do not see the exception logged at my end when hovering with Ctrl on global types.

Do you see the problem in other ts files across other workspaces as well? I have filed the stacktrace and the concern regarding tooltip info for investigation with the dev team. They are looking into it.

Thank you for reporting. Apologies for inconvenience caused.
