Writing a comma in a string that is an argument to a function causes the pop up box to display

[jakegt1]

When writing arguments to functions, the python module shows a pop up box showing the next argument and its documentation, which can be removed by clicking away among other things. However, if you're writing a string as an argument, if you ever write a comma it will cause the popup box to re-fire.

Environment data

• VS Code version: 1.24.1
• Extension version (available under the Extensions sidebar): 2018.6.0
• OS and version: Windows 10
• Python version (& distribution if applicable, e.g. Anaconda): Python 3.5.4
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv
• Relevant/affected Python packages and their versions: N/A

Actual behavior

Pop up box for functions shows when a comma is written inside of a string, not just outside of a string

Expected behavior

Pop up box should not fire if the comma is inside a string

Steps to reproduce:

Write code that would execute a function, add a string as an argument, click to remove the pop up box, write a comma in the string which will show the pop up box.

str("This is my string,")   # Comma causes the box to pop up

Please could you send a screen shot of the pop-up.

Verified.

It is a result of a "hover" request

[DonJayamanne]

@d3r3kk Please retest with the mouse pointer out of the way.

Has nothing to do with hover. Can repro with mouse off screen completely. Nothing appears until I type the comma. Screencap, including the position of the mouse cursor:

Actual mouse hover shows str:[word in string under cursor], not the popup shown above, like so:

Sorry for being poor on my explanation, but ye that's the bug.

[d3r3kk]

@jakegt1 not at all! Thanks very much for the report. (We need to verify each bug reported and it was a lackluster verification on my part if anything!). Now that we are aware of the issue, we'll triage this, probably after the July release, not sure when exactly.

Looks like we need to investigate here:
