Codelens Overlapping after Combining Two Lines

[mjbvz]

• VSCode Version: f977399
• OS Version: Mac 10.12 (16A323)

Steps to Reproduce:

1. Set "typescript.referencesCodeLens.enabled": true
2. Open a ts file that has code lenses on two lines next to each other:

class X {
private z: any
}

Place cursor before at the start of second line and delete the new line

Bug
The two code lenses temporarily are drawn on top of each other (look at the bit with the 18 references text in the gif):

I have changed the behaviour so that a lens disappears when it merges into the line of another, existing lens. The request to recompute lenses will then make it show up again
